New example of acyl cleavage of benzoyl-1,1,1-trifluoroacetone in a three-component synthesis of 4-aryl-2-thioxo-6-phenyl-1,2-dihydropyridine-3- carbonitriles

Dyachenko

, p. 906 - 910 (2012/09/22)

A three-component condensation of aromatic aldehydes, cyanothioacetamide, and benzoyl-1,1,1-trifluoroacetone, involving the acyl cleavage of the latter, results in 4-aryl-2-thioxo-6-phenyl-1,2-dihydro-pyridine-3-carbonitriles. Their alkylation was studied.
