A general route for the synthesis of highly substituted aryl cyclopentanes has been developed involving Diels–Alder reaction of asymmetric dienes prepared from (+)-camphoric acid followed by aromatization of the resulting cyclohexene derivatives. Employing this protocol enantiospecific synthesis of (+)-herbertene and (+)-cuparene has been accomplished.
已开发出合成高度取代的芳基环戊烷的一般方法,涉及由(+)-樟脑酸制备的不对称二烯的Diels-Alder反应,然后将所得环己烯衍生物进行芳构化。采用该方案,已经完成了对(+)-香丹烯和(+)-环戊烯的对映体特异性合成。
