โœฆ Synopsis

Dianions derived from N-Cbz aspartic acid esters undergo highly stereoselective ant/ allylation reactions at the unsubstituted carbon. The roles of additives, of the cation and of the electrophile were studied Synthetic applications and potential utility in peptidomimetic design are also described.

Dianions derived from N-Cbz and N-Boc glutamic acid esters undergo highly stereoselective anti allylation reactions at C-4. The roles of protecting groups and of the electrophile were studied. Synthetic applications and potential utility in peptidomimetic design are also described.
