Abstract
The first organocatalytic asymmetric synthesis of an advanced intermediate of (+)-sarain A was achieved. This approach featured the employment of an organocatalytic asymmetric Michael addition reaction and a nitrogen-to-carbon chirality transfer to forge three chiral centers, as well as a catalytic hydrosilylation for the chemoselective reduction of a key lactam intermediate. The tricyclic intermediate contained all the required functionalities for elaborating into (+)-sarain A.
