摘要
Conversion of tritylated 2-methylglycidol to the corresponding aziridine occurs by Staudinger cyclization of the intermediate azido alcohol. After N-sulfonylation with Ses-Cl and ring-opening with benzyl alcohol, oxidation of the primary alcohol provides N,O-bisprotected alpha-methylserine directly suitable for repetitive peptide synthesis. This sequence represents a general enantioselective protocol for the synthesis of alpha-methylserine and other alpha,alpha-disubstituted amino acids.
