Mannich-type reaction of phenols with iminolactone 4, readily prepared from commercially available phenylglycine, proceeded with high stereoselectivity to give α-arylglycine derivatives. The reaction was also applicable to other electron-rich aromatic compounds and aryl boronic acids. These adducts could be readily converted to the corresponding optically active α-arylglycines.
酚与从商业可得的苯基甘氨酸制备的亚胺内酯4的曼尼赫反应高立体选择性地生成α-芳基甘氨酸衍生物。该反应也适用于其他电子丰富的芳香化合物和芳基硼酸。这些加合物可以方便地转化为相应的光学活性α-芳基甘氨酸。
