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 (TFAIC

A simple and palladium-catalyzed procedure for synthesis of a novel series of potentially biologically active trifluoromethyl-substituted quinazolinones and N-arylquinazoline derivatives via condensation-cyclization reaction of 2-aminobenzamide, 2-amino-N′-arylbenzimidamides and 2-amino-N′-benzylbenzimidamides with trifluoroacetimidoyl chlorides has been developed. noteworthy, this investigation showed the possible of transition-metal-catalyzed activation of trifluoroacetimidoyl chlorides as a carbon trifluoromethylated source for the synthesis of quinazolines and quinazolinone derivatives in good to excellent yields.

A metal-free oxidative cyclization of readily available trifluoroacetimidohydrazides with D-glucose for the assembly of 3-trifluoromethyl-1,2,4-triazoles has been disclosed. D-glucose is applied as C1 synthon to provide methine source in the reaction. Control experiments have been conducted to shed light on the reaction mechanism. The synthetic utility of the protocol has been explored by the implementation of scale up reaction and the synthesis of the key skeleton of NKI-receptor ligand. (Figure presented.).
Elemental Sulfur and Dimethyl Sulfoxide-Promoted Oxidative Cyclization of Trifluoroacetimidohydrazides with Methylhetarenes for the Synthesis of 3-Hetaryl-5-trifluoromethyl-1,2,4-triazoles

A metal-free approach for the synthesis of 3-hetaryl-5-trifluoromethyl-1,2,4-triazoles via sulfur/dimethyl sulfoxide-promoted oxidative cyclization of readily available trifluoroacetimidohydrazides with methylhetarenes has been developed. This transformation proceeds in cascade sulfur-mediated generation of thioaldehyde, condensation, intramolecular cyclization and oxidative aromatization sequence.
