protected chiral γ-amino acetylenic esters have been synthesized using natural occurring amino acids as chiral source. Enantiomerically enriched propargylamines or vinyldibromides have been treated with BuLi at low temperature affording, after carboxylation, enantiomerically enriched derivatives of alkynologous amino esters.
使用天然存在的氨基酸作为手性来源,已经合成了一类新型的不同保护的手性γ-氨基炔属酯。对映体富集的炔丙胺或乙烯基二溴化物已在BuLi的低温下进行了处理,在羧化后,提供了对映体富集的炔基氨基酯衍生物。
