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, arylboronic acids and other nucleophiles. Additionally, several Lewis acid-promoted addition reactions with iminolactone 4 were accomplished efficiently. These adducts could be converted
苯酚与亚氨基内酯 4 的曼尼希型反应(容易由市售的苯基甘氨酸制备)以高立体选择性进行,得到 α-芳基甘氨酸衍生物。该反应也适用于其他富电子芳香族化合物、芳基硼酸和其他亲核试剂。此外,几个路易斯酸促进与亚氨基内酯 4 的加成反应有效地完成。这些加合物可以很容易地转化为相应的光学活性α-氨基酸衍生物。
