Stereocontrolled synthesis of psi[CH = CH] dipeptide isosteres.
A new stereocontrolled synthesis of the psi[CH = CH] dipeptide isostere is described. They key step of the sequence relies on the stereospecific alpha-alkylation of delta-amino-gamma-mesyloxy-alpha,beta-unsaturated esters. The broad availability of nucleophilic alpha-side chains by this method allows the preparation of a wide variety of psi[CH = CH] isosteres with predictable stereochemistry.
