Davies, Alex M. published the artcileValorization of Ethanol: Ruthenium-Catalyzed Guerbet and Sequential Functionalization Processes, SDS of cas: 91-15-6, the main research area is ethanol ruthenium catalyst tandem guerbet alkylation; alc preparation.

A ruthenium-catalyzed tandem Guerbet-alkylation strategy for the valorization of ethanol was reported. The products of ethanol upgrading (higher-order alcs.) undergo subsequent C-C bond forming reactions with four carbon pronucleophiles and one ylide. Studies into catalyst design led to the development of ClRu(5-Mebpi)(PPh3)2 (bpi = 1,3-bis(2′-pyridylimino)isoindolate) as a highly efficient catalyst for producing biofuels and value-added chems. from ethanol via Guerbet and tandem Guerbet reactions. This catalyst affords 65% higher-order alcs. in short reaction times (2 h), providing the highest TON (155,890) and TOF (12,690 h-1) for a homogeneous catalyst reported to date.

Cycloisomerizations are powerful skeletal rearrangements that allow the construction of complex mol. architectures in an atom-economic way. Here an unusual type of cyclopropyl enyne cycloisomerization that couples the process of a cycloisomerization with the activation of a C-C bond in cyclopropanes was presented . A set of substituted non-canonical tricyclic cyclobutanes were synthesized under mild conditions using [(Ph3P)2Fe(CO)(NO)]BF4 as catalyst in good to excellent yields with high levels of stereocontrol.

Abel-Snape, Xavier published the artcileSynthesis of Indenes and Benzofulvenes via a Palladium-Catalyzed Three-Component Reaction, Formula: C7H6N2, the main research area is indene benzofulvene preparation palladium catalyst three component reaction.

A palladium-catalyzed three-component domino reaction to access indene derivatives is reported. This reaction proceeds via the sequential formation of three bonds: the first two resulting from inter- and intramol. carbopalladation and the final bond arising from an attack by a terminating nucleophilic reagent. Modifying the starting tether on the iodoarene led to either indenes or benzofulvenes. Three termination variations were compatible with this sequence, which furnished products in moderate to good yields. The oxabicycle used in this work acts as an acetylene surrogate, which is revealed in a postcatalytic retro-Diels-Alder step. A diastereomerically enriched mixture of oxabicyclic derivatives allowed for preliminary results for the enantioselective synthesis of indenes.

Lang, Simon B. published the artcileActivation of Alcohols with Carbon Dioxide: Intermolecular Allylation of Weakly Acidic Pronucleophiles, COA of Formula: C16H13NO, the main research area is nitroalkane allyl alc carbon dioxide palladium allylation catalyst; nitrile allyl alc carbon dioxide palladium allylation catalyst; aldehyde allyl alc carbon dioxide palladium allylation catalyst; allylated product preparation.

The direct coupling of allyl alcs. with nitroalkanes, nitriles, and aldehydes using catalytic Pd(PPh3)4 has been accomplished via activation of C-OH bonds with CO2. The in situ formation of carbonates from alcs. and CO2 facilitates oxidative addition to Pd to form reactive π-allylpalladium intermediates. In addition, the formation of a strong base activates nucleophiles toward the reaction with the π-allylpalladium electrophile. Overall, this atom economical reaction provides a new C-C bond without the use of an external base and generates water as the only byproduct.

Faroughi Niya, Homayoun published the artcileA One-pot Multicomponent Synthesis of Pyrroloacridine-1(2H)-one and 1,8-Dioxodecahydroacridine Derivatives Catalyzed by Salicylic Acid in Polyethylene Glycol, Quality Control of 1885-29-6, the main research area is pyrroloacridinone dioxodecahydroacridine preparation green chem; aniline aldehyde dimedone multicomponent reaction salicylic acid catalyst; isatine aniline dimedone multicomponent reaction.

Two efficient, straightforward and ecofriendly protocols are described for one-pot multicomponent synthesis of pyrrolo[2,3,4-kl]acridin and 1,8-dioxodecahydroacridine derivatives using salicylic acid as the catalyst and polyethylene glycol (PEG-200) as the promoter solvent. The reported approach shows significant advantages, such as operational simplicity, the use of an inexpensive and nontoxic catalyst, high yields, short reaction time, and the product isolation ease without chromatog. separation An important feature of this work is the route of the reaction that depends on the reaction solvent.

Zhang, Guofu published the artcileA cascade process for directly converting nitriles (RCN) to cyanamides (RNHCN) via SO2F2-activated Tiemann rearrangement, Related Products of nitriles-buliding-blocks, the main research area is cyanamide preparation atom economy; amidoxime key intermediate preparation Tiemann rearrangement sulfonyl difluoride promoted; nitrile hydroxylamine oximation.

A simple, mild and practical process for the direct conversion of nitriles RCN (R = H, t-Bu, 2-thienyl, 4-ClC6H4, etc.) to cyanamides RNHCN was newly discovered and exhibited a wide substrate scope as well as great functional group-tolerability (36 examples). In this efficient strategy, in situ generated amidoximes R(NH2)C:NOH obtained from the reaction of nitriles with hydroxylamine subsequently underwent Tiemann rearrangement, producing corresponding cyanamides with great isolated yields under SO2F2. Addnl., the control experiments reportedly shed light on tentative mechanism involved in formation and elimination of key intermediate: a sulfonyl ester.

Krasavin, Mikhail published the artcileContinued exploration of 1,2,4-oxadiazole periphery for carbonic anhydrase-targeting primary arene sulfonamides: discovery of subnanomolar inhibitors of membrane-bound hCA IX isoform that selectively kill cancer cells in hypoxic environment, COA of Formula: C6H4N2, the main research area is oxadiazole arenesulfonamide preparation antitumor carbonic anhydrase inhibitor hypoxia SAR; 1,2,4-Oxadiazole; Cancer cells; Carbonic anhydrase; Hypoxic environment; Isoform-selective inhibitors; Isosteric replacement; Periphery groups; Primary sulfonamides; Subnanomolar inhibition.

An expanded set of diversely substituted 1,2,4-oxadiazole-containing primary aromatic sulfonamides I (R1 = cyclopropyl, Ph, 2-MeOC6H4, 3-MeOC6H4, pyridin-2-yl) and II (X = m-phenylene, p-phenylene, thiophene-2,4-diyl, etc.; R2 = Me, cyclopropyl, Ph, thiophen-2-yl, etc.) was synthesized and tested for inhibition of human carbonic anhydrase I, II, IX and XII isoforms. The initial biochem. profiling revealed a significantly more potent inhibition of cancer-related, membrane-bound isoform hCA IX (reaching into submicromolar range), on top of potent inhibition of hCA XII that is another cancer target. The observed structure-activity relationships have been rationalized by mol. modeling. Comparative single-concentration profiling of the carbonic anhydrase inhibitors synthesized for antiproliferative effects against normal (ARPE-19) and cancer (PANC-1) cell lines under chem. induced hypoxia conditions revealed several candidate compounds selectively targeting cancer cells. More in-depth characterization of these leads revealed two structurally related compounds that showed promising selective cytotoxicity against pancreatic cancer (PANC-1) and melanoma (SK-MEL-2) cell lines.

A synergetic copper/zinc-catalyzed one-step annulation reaction of 2-amino (hetero)arylnitriles e.g., 2-aminobenzonitrile with ynamide-derived buta-1,3-diynes R1N(S(O)2R)CCCCN(S(O)2R)R1 (R = Bn, Me; R1 = Me, Ph, 4-methylphenyl, etc.) to deliver 1H-pyrrolo[3,2-c]quinoline-2,4-diamine derivatives I (R2 = H, 8-Me, 7-Cl, 9-F, etc.) in moderate to good yields was reported. The annulation reaction follows a double cyclization pathway. The gram-scale synthesis of 1H-pyrrolo[3,2-c]quinoline-2,4-diamine proves the practicality of this protocol.
