Diels-Alder reaction of cis-1,4-diacetoxy-2-cyclopentene with cyclopentadiene gave a tricyclo[5.2.1.02,6]decene derivative stereoselectiviely. The titled dienone useful for enantioselective synthesis of cyclopentanoids and other natural products has been efficiently prepared from the adduct by means of dissymmetrization with lipase-catalyzed acetylation.
顺式-1,4-二乙酰氧基-2-环戊烯与环戊二烯的Diels-Alder反应立体选择性地得到三环[5.2.1.02,6]癸烯衍生物。通过脂肪酶催化乙酰化的不对称化,从加合物有效地制备了可用于对映选择性合成环戊烷和其他天然产物的题为二烯酮。
