3-Alkyl-, 3-aryl-, and 3-deuteriotropilidenes are prepared in 21–29% yields by the dehydration of the corresponding 1-substituted 2,6-cycloheptadienols with boric acid. The present method provides an unambiguous route to the title compounds.
通过用硼酸对相应的 1-取代 2,6- 环庚二烯醇进行脱水,以 21-29% 的产率制备 3-烷基-、3-芳基-和 3-deuteriotropilides。本方法提供了获得标题化合物的明确途径。
