Stereoselective and Site-Specific Allylic Alkylation of Amino Acids and Small Peptides via a Pd/Cu Dual Catalysis

We report a stereoselective and site-specific allylic alkylation of Schiff base activated amino acids and small peptides via a Pd/Cu dual catalysis. A range of noncoded α,α-dialkyl α-amino acids were easily synthesized in high yields and with excellent enantioselectivities (up to >99% ee). Furthermore, a direct and highly stereoselective synthesis of small peptides with enantiopure α-alkyl or α,α-dialkyl α-amino acids residues incorporated at specific sites was accomplished using this dual catalyst system.

Synthesis of Antiarrhythmic Peptide by Solution Phase

Synthesis of antiarrhythmic peptide, Gly-Pro-Hyp-Gly-Ala-Gly by solution phase procedure is described.The OH group of 4-hydroxyproline, present in the sequence has been left unprotected throughout the synthesis.No acylation of the OH group has been observ

2 AND 3-SUBSTITUTED ENKEPHALINS

Analogs of enkephalin having agonist activity at opiate receptors are disclosed herein. These analogs are useful as analgesics, non-addicting narcotic antagonists and anti-diarrheal agents.
