(−)-α-Pinene 1 has been restructured into a chiral cyclohexenone (+)-6, in which the functionalities were integrated to afford bicyclo[3.3.1]nonan 3,7-diones and a novel tricyclic skeleton 16 related to the sesquiterpene clovene. Intramolecular [2+2] photocycloadditions in (+)-6 and related 5-alkenylcyclohexenones provided an entry into some novel bridged tricyclic systems.
(-)-α-P烯1已重整为手性环己烯酮(+)- 6,其中整合了官能团以提供双环[3.3.1]壬南3,7-二酮和与该环相关的新型三环骨架16倍半萜烯丁香。(+)- 6和相关的5-烯基环己烯内的分子内[2 + 2]光环加成反应为某些新型桥联三环系统的进入提供了条件。
