The acid catalysed interaction in dioxan of trialkyl orthoformates with diisophor-2(7)-en-ol-3-one, diisophor-2(7)-en-ol, and their bisnor-homologues, provides the corresponding 1-alkoxy-compounds. Their structure is established by the identity of -methoxydiisophor-2(7)-en-3-one obtained by this method, and by the action of sodium methoxide on 1-chlorodiisophor-2(17)-en-3-one. The latter is regenerated
酸催化原甲酸三烷基酯的二恶烷与diisophor-2(7)-en-ol-3-one,diisophor-2(7)-en-ol和它们的bisnor同源物的相互作用,提供了相应的1-烷氧基化合物。它们的结构是由通过这种方法获得的-甲氧基二isophor-2(7)-en-3-one的身份以及甲醇钠对1-氯二isophor-2(17)-en-3-one的作用所确定的。后者在氯化锡-乙酰氯的作用下从1-甲氧基(或乙氧基)二异佛尔-2(7)-en-3-one再生。催化加氢将1-烷氧基二异佛尔-2(7)-en-3-ones中的3-酮官能团还原为亚甲基单元;在1-异丙氧基-同源物的情况下,同时除去1-烷氧基可得到该系列的倒数第二个母体烃,二异佛尔-2(7)-烯。
