Optically pure oxodicyclopentadiene (KDP) has been prepared in both enantiomeric forms from racemic 4-tert-butoxycyclopent-2-en-1-one in three ways starting from 4-tert-butoxycyclopent-2-en-1-one involving contra-steric Diels-Alder reaction and lipase-mediated enantiospecific kinetic transesterification as key steps.

环戊二烯酮(KDP)已通过三种方法从外消旋的4-叔丁氧基环戊-2-烯-1-酮制备出两种对映异构体形式,这些方法涉及反位立体选择性的Diels-Alder反应和脂酶介导的对映选择性动力学转酯化反应作为关键步骤。
