Aliphatic, aromatic, and heteroaromatic aldehydes were readily converted to corresponding nitriles in a one-pot reaction sequence with hydroxylamine and sulfuryl fluoride. The reaction proceeds at room temperature, does not require metal catalysts and special precautions, and produces nitriles in excellent yields. It is compatible with a variety of functional groups, can be performed in aqueous and organic solvents, and is readily scalable to multigram quantities. Mild conditions and high selectivity of the reaction enabled the construction of polyfunctional probes containing nitrile, alkyne, azide, and fluorosulfate groups for further orthogonal derivatization.

Herein, a vanadium-based material V-N-C-700 was prepared via a simple and convenient method, and employed for liquid-phase catalytic ammoxidation of alcs. RCH2OH (R = n-Bu, Ph, pyridin-2-yl, etc.) with mol. oxygen. By using V-N-C-700/2-picolinic acid, primary aromatic alcs. were smoothly converted into the amides RC(O)NH2 and nitriles RCN in the presence of urea. The corresponding aldehydes RCHO are the key intermediates, and 2-picolinic acid could significantly enhance oxidation of alcs. into aldehydes. The amides were formed simultaneously along with nitriles, rather than only from nitriles via successive hydration. This work further expands non-noble metal catalysts for the preparation of amides and nitriles.

Switchable chemoselective conversion of 2-amido-aryl oxazolines to quinazolin-4(3H)-ones or N-(2-chloroethyl)benzamides was achieved. The former reaction was proposed to involve a PIFA-mediated 6π electrocyclization followed by an in situ nucleophilic substitution, while the latter reaction uses aluminum chloride as a halogenated source through a ring-opening reaction. The reactions proceed smoothly under mild conditions and have excellent functional group compatibility.

Ielo, Laura published the artcileTelescoped, Divergent, Chemoselective C1 and C1-C1 Homologation of Imine Surrogates: Access to Quaternary Chloro- and Halomethyl-Trifluoromethyl Aziridines, Formula: C7H6N2, the main research area is chloro halomethyl trifluoromethyl aziridine preparation chemoselective homologation imine; aziridines; carbenoids; chemoselectivity; homologation; lithium.

A conceptually novel, high-yielding, mono- or bis-homologation was realized with lithium halocarbenoids and enables the one-step, fully chemocontrolled assembly of a new class of quaternary trifluoromethyl aziridines. Trifluoroacetimidoyl chlorides (TFAICs) act as convenient electrophilic platforms, enabling the addition of either one or two homologating elements by simply controlling the stoichiometry of the process. Mechanistic studies highlighted that the homologation event, carried out with two different carbenoids (LiCH2Cl and LiCH2F), leads to fluoromethyl analogs in which the first nucleophile was employed for constructing the cycle and the second for decorating the resulting mol. architecture.

Krapf, Michael K. published the artcileSynthesis and biological evaluation of quinazoline derivatives – A SAR study of novel inhibitors of ABCG2, HPLC of Formula: 1885-29-6, the main research area is quinazoline derivative preparation ABCG2 inhibitor multi drug resistance; ABC transporter; ABCG2; Inhibitor; Quinazolines; SAR.

Multidrug resistance (MDR) is a major obstacle for effective chemotherapeutic treatment of cancer frequently leading to failure of the therapy. MDR is often associated with the overexpression of ABC transport proteins like ABCB1 or ABCG2 which efflux harmful substances out of cells at the cost of ATP hydrolysis. One way to overcome MDR is to apply potent inhibitors of ABC transporters to restore the sensitivity of the cells toward cytostatic agents. This study focusses on the synthesis and evaluation of novel 2,4-disubstituted quinazoline derivatives regarding the structure-activity-relationship (SAR), their ability to reverse MDR and their mode of interaction with ABCG2. Hence, the inhibitory potency and selectivity toward ABCG2 was determined Moreover, the intrinsic cytotoxicity and the reversal of MDR were investigated. Interaction type studies with the substrate Hoechst 33342 and conformational analyses of ABCG2 with 5D3 monoclonal antibody were performed for a better understanding of the underlying mechanisms. In our study we could further enhance the inhibitory effect against ABCG2 (compound I, IC50: 55 nM) and identify the structural features that are crucial for inhibitory potency, the impact on transport activity and binding to the protein.
