Abstract

A facile five-step route to the naturally occurring CD45 protein tyrosine phosphatase inhibitor, (Z)-pulchellalactam, with 64% overall yield has been demonstrated starting from citraconimide (5) via regioselective NaBH4 reduction, catalytic hydrogenation, resin-catalyzed dehydration, N-BOC protection, and stereoselective condensation pathway.
