A new approach to the stereoselective synthesis of conveniently protected α-allyl substituted amino acids; chiral key compounds in the synthesis of constrained peptide isostere constituents
摘要:
Enantiomerically pure alpha-allyl-N-Boc-aminoamides were prepared by Curtius rearrangement of alpha,alpha-dialkyl chiral 2-cyanoesters obtained by the diastereoselective allylation of chiral 2-cyanoesters according to a modification of our previously described procedure.
