A general and efficient strategy for the synthesis of protected α-aminoacids is reported. The method uses malonate derivatives as the starting materials and Cs2CO3 as a base at 60 degrees, giving α-aminoacidderivatives in moderate yields by releasing CO2. This methodology shows broad substrate scope (primary and secondary acids), excellent functional group tolerance and high efficiency to give the
报道了一种合成保护的α-氨基酸的通用有效策略。该方法以丙二酸酯衍生物为起始原料,以Cs 2 CO 3为碱在60度下,通过释放CO 2,以中等收率得到α-氨基酸衍生物。该方法学显示了广泛的底物范围(伯酸和仲酸),出色的官能团耐受性和高效率,可在温和的反应条件下提供所需的产物。它还允许构建β和γ-氨基酸以及其他非天然产物。
