摘要 4种金鸡纳生物碱-9-O-脯氨酸酯衍生物用于催化环己二酮与溴乙酰甲酸乙酯的不对称"中断的"Feist-Bénary反应,得到了高的化学产率(>92%)和最高为72%e.e.的立体选择性。 Four cinchona alkaloid-9-O-proline ester deriva- tives were used to catalyze the asymmetric " interrupted " Feist-Benary reaction of ethyl bromopyruvate bromo-ketoesters and 1,3-cyclohexadione. The corresponding hydroxydihydro- furans were obtained in excellent yields ( 〉 92% ) and with up to 72% e. e..
