Abstract The application of an allylic strain effect in boron enolates and asymmetric Michael-like addition/electrophilic bromination reactions is reported for the asymmetric synthesis of the individual isomers of unusual constrained amino acids. For β-substituted α-amino acids, all of the final optically pure products were identical to authentic samples, which provided further and unequivocal evidence
摘要报道了烯丙基应变效应在硼烯醇化物和不对称迈克尔样加成/亲电溴化反应中的应用,用于不对称合成个别受限氨基酸的异构体。对于β-取代的α-氨基酸,所有最终的光学纯产品都与真实样品相同,这为确认本报告中新方法的立体化学控制的分配提供了进一步明确的证据。
