Starting from allo-cyclogeranic acid, 3-methyl-4-allo-cyclogeranylbut-2-ene-oic acid has been prepared. This monocyclic compound has been converted into a bicyclic isomer, for which a spiroeyclic structure is assigned. It represents a further new type of synthetic bicyclic sesquiterpenes.
从别基环
香叶酸开始,已经制备了3-甲基-4-烷基环香兰基丁-2-烯-
油酸。该单环化合物已被转化为双环异构体,为其分配了螺环结构。它代表了另一种新型的合成双环
倍半萜烯。
