(+/-)-2-Hydroxymethylbicyclo[2.2.1]hepta-2,5-diene. (+/-)-2-acetoxymethylbicyclo[2.2.1]hepta-2,5-diene and their hexachlorinated derivatives were resolved via CCL- and PLE-catalysed hydrolysis to afford enantiomerically enriched products with e.e.s of 61-93%. The absolute configurations were determined by transforming 2-hydroxymethylbicyclo[2.2.1]hepta-2,5-diene into the 2-formylbicyclo[2.2.1]hepta-2,5-diene with known absolute configuration.

(±)-2-羟甲基双环[2.2.1]戊烷-2,5-二烯及其醋酸酯衍生物以及它们的六氯代物通过CCL-和PLE催化的水解反应被分解,得到了对映体过量百分比(e.e.s)为61-93%的对映体富集产物。绝对构型通过将2-羟甲基双环[2.2.1]戊烷-2,5-二烯转化为具有已知绝对构型的2-甲酰基双环[2.2.1]戊烷-2,5-二烯来确定。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
