The first total synthesis of the 14-membered para ansa cyclopeptide alkaloid (-)-nummularine F is reported. The pivotal transformations of the synthetic strategy are (1) a stereocontrolled approach for introducing the absolute stereochemistry at the α- an
Studies directed toward the total synthesis of 14-membered cyclopeptide alkaloids: Synthesis of a cyclic precursor to nummularine-F

A highly strained 14-membered para-ansa cyclopeptide, a potential precursor of the cyclopeptide alkaloid, nummularine-F, was made by cyclization of a pentafluorophenyl ester under catalytic hydrogenation conditions. This cyclization and the stereoselective synthesis of the acyclic activated ester from D-serine, are presented.
