series of difluoromethyl-containing α-acyloxycarboxamide derivatives were synthesized through a Passerini reaction of acids, aldehydes, and phenylsulfanyl-protected difluorinated isocyanide followed by meta-chloroperoxybenzoic acid mediated oxidation and the removal of the phenylsulfonyl protecting group. The unexpected formation of deacylation products from the reaction between the Passerini products
通过酸、醛和苯硫基保护的二氟异氰化物的 Passerini 反应,然后间氯过氧苯甲酸介导的氧化和苯磺酰基保护基团的去除,合成了一系列含二氟甲基的 α-酰氧基甲酰胺衍生物。还报道了由 Passerini 产物与 Bu3SnH/偶氮二(异丁腈)之间的反应意外形成的脱酰产物。
