An efficient and practical method for the synthesis of 4-aminoquinoline derivativeswas developed via copper-catalyzed cascade cyclization of 2-aminobenzonitrile and nitroolefins. This reaction proceeded through a consecutive Michael addition/cyclization/oxidization protocol, providing 4-aminoquinolines with moderate to excellent yields under mild conditions. This method features readily available materials, one-pot one-step operation, and proceeded without bases.

Mettry, Magi; Moehlig, Melissa P.; Hooley, Richard J. published the artcile< Synthesis, Guest Binding, and Metal Coordination of Functionalized Self-Folding Deep Cavitands>, Quality Control of 6136-93-2, the main research area is cavitand self folding preparation guest binding metal coordination.

A simple method to introduce donor functions to the upper rim of self-folding benzimidazole-based deep cavitands is described. The upper rim donors allow controlled noncovalent binding of suitably sized guest species via both self-complementary hydrogen bonding and space-filling interactions; and metal-mediated self-folding is possible if bidentate coordinators are incorporated.

Yadav, Maruti B.; Jeong, Yeon Tae published the artcile< A one-pot ring-closure and ring-opening sequence for the cascade synthesis of dihydrofurofurans and functionalized furans>, COA of Formula: C9H6ClNO, the main research area is dihydrofurofuran furan preparation triethylamine catalyst; aromatic aliphatic glyoxal cyanoacetophenone three component ring closure opening.

Authors have developed a simple novel ring-closure and ring-opening pathway using an organo-base system for the synthesis of highly substituted dihydrofurofuran and furan frameworks via a triethylamine-catalyzed one-pot three-component reaction. The protocol involved a Knoevenagel and Michael adduct via Paal-Knorr cyclization with aromatic/aliphatic glyoxal and 2-cyanoacetophenone under mild and heating conditions with excellent yields through a simple filtration method. The merits of this methodol., including the use of easily available feedstocks and an inexpensive catalyst, Gram-scale synthesis, wide functional group tolerance, an open-air reaction setup, and no need for workup and column-chromatog. procedures, make the developed methodol. a practical way to access dihydrofurofurans and functionalized furans.

The authors herein report an Ir-catalyzed enantioselective C(sp3)-H borylation of cyclopropanecarboxamides using a chiral bidentate boryl ligand for the 1st time. A variety of substrates with α-quaternary C centers could be compatible in this reaction to provide β-borylated products with good to excellent enantioselectivities. Also the borylated products can be used as versatile precursors engaging in stereospecific transformations of C-B bonds, including the synthesis of a bioactive compound Levomilnacipran.

The hydrolytic imidazoline ring expansion (HIRE) methodol. was extended to readily available tetracyclic [1,4]thiazepines as well as sulfoxide and sulfone analogs thereof. The reactions resulted in the facile formation of a rare medium-sized [1,4,7]thiazecine ring system that has an emerging utility in bioactive compound design. Comparing the HIRE rates for representative compounds in the three groups of substrates allowed drawing some generalizations about the substituent effects on the course of the reaction.

A new transformation pattern for enantioselective intramol. hydroacylation has been developed involving an alkene isomerization strategy. Proceeding through a five-membered rhodacycle intermediate, 3-enals such as I (or their Z isomers) were converted to C3- or C3,C5-chirogenic cyclopentanones such as II with satisfactory yields, diastereoselectivities, and enantioselectivities. A catalytic cycle has been theor. calculated and the origin of the stereoselection is rationally explained.
