The utility of these promoters to achieve an efficient coupling of a-amino (3-lactams with a-amino acid esters has also been documented [89]. For example, (3-lactam 51, Scheme 19, upon treatment with (S)-PheOMe and (S)-ValOMe in DMF, in the presence of NaN3, furnishes dipeptides 52 and 53 respectively, in good... [Pg.224]
