CYCLIC DERIVATIVES OF 3,3-DIPHENYLALANINE (DIP) (II), NOVEL α-AMINO ACIDS FOR PEPTIDES OF BIOLOGICAL INTEREST

The chiral and achiral syntheses of novel cyclic derivatives of 3,3-diphenylalanine (DIP) are described.

Cyclic amino acids and derivatives thereof

Novel cyclic amino acids which are useful in preparing biologically active peptides as well as a process for the preparation of D and L enantiomers of the cyclic amino acids are described where an N-protected derivative of the racemic cyclic amino acid is treated with (-)cinchonidine and the resulting salt resolved into the desired enantiomers, as well as derivatives thereof and valuable intermediates used in the process.
