reaction of natural amino acids (glycine, β-alanine, γ-aminobutyric and ɛ-aminocapronic acids, d,l-valine, d,l-leucine, anthranilic acid) with bielectrophilic acylacetylenes proceeds chemo-, regio- and stereospecifically in the presence of NaOH (45–50 °C, 4 h, EtOH–H2O) to give (after treatment of the reaction mixture with aqueous HCl) Z-isomers of N-acylvinyl derivatives of amino acids in 87–94% yield
的天然氨基酸(甘氨酸,所述一锅反应β丙氨酸,γ γ-氨基和ɛ氨基己酸,d,升-缬氨酸,d,升-亮氨酸,邻氨基苯甲酸)与bielectrophilic acylacetylenes进行化疗,区域选择性和在NaOH(45–50°C,4 h,EtOH–H 2 O)存在下进行立体定向生成(在用HCl水溶液处理反应混合物后)N–氨基酸乙烯基衍生物在87–94中的Z-异构体% 屈服。
