asymmetric synthesis of chiral α-keto esters was required. These compounds can be conveniently generated in 51–84% yields via Grignard addition to either symmetrical or mixed oxalates at −40°C in tetrahydrofuran. The reaction works equally well with aliphatic or aromatic Grignard reagents.
在进行含氯代谢物(-)-隐孢子菌素的不对称合成的过程中,需要有效且可靠的手性α-酮酸酯的不对称合成。通过在40°C于四氢呋喃中的对称或混合草酸盐形式的格氏添加剂,可以方便地以51-84%的产率生成这些化合物。该反应与脂肪族或芳香族格氏试剂同样有效。
