Аннотация

Multicomponent reactions of ethyl 1-trifluoromethyl-2-(trimethylsilyloxy)cyclopropanecarboxylate, isonitriles, and either 2-aminopyridine or amino acids provided imidazo[1,2-a]pyridines or γ-lactams, respectively. This access to trifluoromethyl-substituted heterocycles demonstrates again that siloxycyclopropanes can serve as hidden functionalized aldehydes and that this type of donor–acceptor-substituted cyclopropanes is particularly versatile.
