✦ Synopsis


Acetylene-containing amino acids, obtained in enantiopure form via an enzymatic resolution process, serve as versatile intermediates in the synthesis of various highly functionalized heterocycles. The key transformations, intramolecular OC-and NC-bond formation, proceed via Pd-catalysis.

Enantiomerically pure acetylene-containing aamino acids were used as versatile starting materials for the synthesis of a variety of heterocycles via Pd-mediated cyclization reactions. Depending on the protecting group strategy, both the carboxylate and the amine function of the amino acids could par
