Popis: | We describe a simple chiral-pool synthesis of (–)-longamide B, (–)-longamide B methyl ester, and (–)-hanishin. The key feature of the total synthesis is the formation of a piperazinone from a 1,2-cyclic sulfamidate and methyl 2-pyrrolecarboxylate, which permits efficient construction of the pyrrolopiperazinone core scaffold. |
