A solid-phase synthesis of new N-substituted valienamines has been developed and new synthesis of (+/-)-conduramine F-1, (-)-conduramine F-1, and (+)-ent-conduramine F-1 is presented, together with the preparation of N-benzylated conduramines F-1. N-Benzylation of both valienamine and (+)-ent-conduramine F-1 improves their inhibitory activity toward alpha-glucosidases significantly. The additional hydroxymethyl group makes valienamine derivatives more active than their (+)-ent-conduramine F-1 analogues.
