Abstract: The enantioselective synthesis of both enantiomers of the N-Moc phenylglycine derivatives is reported. The synthetic strategy shows the influence of N-protecting groups in the enantioselective deprotonation and carboxylation of N, N-protected benzylamine 1 using s-BuLi◊(-)-sparteine complex 4 as chirality source. Key words: enantioselective deprotonation,(-)-sparteine, carboxylation, silicon rearrangement, phenylglycine
