dc.description.abstract本論文以經由雙半縮醛(diheniacetal)化合物3的合成途徑,進行臭氧裂解反應,合成出在骨架上含有四個氧原子且apex碳上具有烯基及羰基之籠狀化合物4及5。 利用apex碳上具有烯基及羰基之骨架上含有四個氧原子的籠狀化合物4及5進行親電子性反應及新核性反應,探討反應之立體面向選擇性,皆得到高比例之anti-attack產物。 經相同的反應出發物雙半縮醛(diheniacetal)化合物3,進行碘誘導環化反應,接著使用強鹼(KH)進行分子內環化反應,合成出在骨架上含有三個氧原子且apex碳上具有烯基之籠狀化合物17。 本論文以易於製備且產率高之碳6位置上具有不同取代基的fulvene為出發物,合成在骨架上含有二個氧原子之籠狀化合物,探討不同出發物在合成骨架上具有二個氧原子之籠狀化合物在產率上的差異。 利用在骨架上含有二個氧原子且apex碳上具有烯基及羰基之籠狀化合物37及40探討反應之立體面向選擇性。zh_TW
dc.description.abstractThe syntheis of the tetreaacetal tetraoxa-cage compounds 4 and 5 with alkene group or carbony1 group on the apex carbon have been accomplished from ozonoluysis of dihemiacetal compound 3. Reaction of the tetraoxa-cages 4 and 5 with electrophiles and nucleophiles exclusively gave the correstonding anti-attack products. The synthesis of diacetal trioxa-cage compound with olefine group on the apex carbon 17 from dihemiacetal compound 3 by iodine-induced cyclization reaction is reported. The synthesis of dioxa-cages compounds with different substituted groups on the apex carbon is reported. The π-facial selectivities of the dioxa-cages 37 and 40 with electrophiles and nucleophiles are also demonstrated.en_US
