Pd-Catalyzed cyclization reactions of acetylene-containing α-amino acids
摘要:
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. (C) 1998 Elsevier Science Ltd. All rights reserved.
