Indium-Catalysed Multicomponent Reaction of Acetals with Dibenzylamine and Alkynes
摘要:
A reaction of acetals with dibenzylamine and alkynes to form propargylamines has been developed via the activation of both C(sp3)-O and C(sp)-H bonds by InCl3. The iminium ion has been found to be the key intermediate.
