such as hydroazulene 2, bicyclooctane 4, or hydrindanone 12 can be easily obtained by Amberlyst 15 (A 15) catalyzed cyclizations of allyl- and propargylsilanes. The total syntheses of (±)-β-pinguisene 5 and (±)-pinguisenol 6 have been achieved by propargylsilane-terminated cyclizations of enone 11 as the key step. Compound 12 was transformed in a straight forward way to provide β-pinguisene 5 and pinguisenol
重要的环骨架,例如氢az 2,双环辛烷4或氢化达酮12可通过Amberlyst 15(A 15)催化的烯丙基和炔丙基硅烷的环化反应轻松获得。作为关键步骤,已通过烯丙基11的炔丙基硅烷封端的环化反应实现了(±)-β-异戊烯烯5和(±)-异戊烯醇6的总合成。以简单的方式将化合物12转化以提供β-庚二烯5和品吉森醇6。
