<i>sec</i>-Alkylketoximes in the Trofimov reaction: from minor products to reagents of the XXI century

Abstract

This review summarizes the results and perspectives of studies of the reaction between sec -alkylketoximes having only one C-H bond at the α-position to the oxime function and acetylene in the presence of superbasic catalytic media. Selective syntheses of key intermediates of pyrroles assembly (3 H -pyrroles and 5-hydroxypyrrolines), their reactivity, and unique cascade assemblies of unpredictable products are discussed.
