Carbamoyloxy groups show syn-stereodirecting effect on epoxidation of allylic and homoallylic double bonds similar to that of hydroxy groups. Allylic carbamates –, , , and and their homoallylic counterparts – thus produce corresponding -epoxides as the major products on reaction with MCPBA. Mechanism of this steering is discussed.
