Abstract

In recent years, the gold-catalyzed rearrangement reactions of propargylic esters have received considerable attention owing to their synthetic utility in a wide variety of fascinating transformations.[1] Two main competitive processes, namely, 1, 2-acyloxy migration [2] and 3, 3-rearrangement [3] are usually involved in most cases of these gold-catalyzed rearrangement reactions as an initial step, which depends on the substitution patterns on ...
