2-Phenallyl was found to be a versatile protecting group of primary amines for the asymmetric one-pot three-component synthesis of propargylamines which leads to enantiomeric excess of up to 96%; it can be easily removed with a palladium(0)-catalyzed allylic substitution using 1,3-dimethylbarbituric acid as a nucleophile.
                                    2-苯偶酰是一种对
伯胺具有多种保护作用的保护基团,它在不对称一锅法三组分合成
炔丙胺的过程中,能够使得对映体过量度高达96%;通过使用
1,3-二甲基巴比妥酸作为亲核试剂,进行
钯(0)催化下的烯丙基取代反应,可以轻松地将之移除。
