✦ Synopsis


The asymmetric syntheses of D-(R)-(-)-and L-(S)-(+)-3,3diphenylahmine (Dip) are described

Currently, there is great interest in the design and synthesis of unusual a-amino acids which may provide specific conformational restraint, and also biostability to degradation by peptidases to small peptides/peptidomhnetics
