- Abstract
Abstract: Cyclic carbamates were synthesized by the acid‐catalyzed reaction between Boc‐protected aminals as an imine precursor and 4‐methoxyphenyl‐substituted alkynes. The resulting cyclic carbamates could be converted to the one carbon ring‐contracted cyclic carbamates by ozonolysis. Consequently, 4‐methoxyphenyl‐substituted alkynes served as masked acyl anion equivalents.
