1,2-Asymmetric induction in dianionic allylation reactions of amino acid derivatives-synthesis of functionally useful, enantiopure aspartates and constrained scaffolds
摘要:
Dianions derived from N-Cbz aspartic acid esters undergo highly stereoselective anti 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. (C) 1998 Elsevier Science Ltd.
