organolithium reagents derived from l-serine have been generated and reacted with electrophiles. The novel enantiomerically pure adducts thus obtained were then converted, through β-amino alcohols, into novel non-proteinogenic α-amino acids. The methodology also made available a novel boronic acid which was then employed as a Suzuki cross-coupling partner, elaborating a new pathway to phenylalanine analogues
已经产生了衍生自1-丝氨酸的高手性,高度官能化的有机锂试剂,并使其与亲电子试剂反应。然后将由此获得的新型对映体纯的加合物通过β-氨基醇转化为新型的非蛋白生成的α-氨基酸。该方法还提供了一种新型硼酸,然后将其用作Suzuki交叉偶联伴侣,为苯丙氨酸类似物开辟了一条新途径。
