DIASTEREOSELECTIVE SYNTHESIS OF AN α, β-DIAMINOCARBOXYLIC ACID : AN EFFICIENT SYNTHESIS OF FR900490, AN IMMUNOMODULATING PEPTIDE ISOLATED FROM A FUNGUS

Abstract

A practical synthesis of FR900490 (1__-), a peptidyl immunomodulator of microbial origin, has been achieved through diastereoselective preparation of α, β-diaminobutyric acid 2__-.
