ENANTIOSELECTIVE SYNTHESIS OF (-)-GHEPHYROTOXINE 223AB

A highly enantioselective synthesis of the dendrobatid indolizidine alkaloid 223AB is described using a chiral amino acid as starting material.

Total synthesis of (+) monomorine I from chiral cyclic β-enamino estrer

We describe the total synthesis of (+) monomorine I 1 and the preparation of cis-2,5-disubstituted functionalized pyrrolidines via cyclic β-enamino esters 4, starting from (S)-pyroglutamic acid.
