Interception of an iminium ion equivalent by intramolecular nucleophilic attack by a silyl ether during lithium aluminium hydride reduction of a tertiary lactam
Abstract
The efficient formation of a bicyclic oxazolidine by lithium aluminium hydride reduction of a tertiary amide provides an example of intramolecular nucleophilic capture of an iminium ion equivalent by the oxygen of a silyl ether.
