| Summary: | 碩士 === 國立交通大學 === 應用化學系 === 87 === The synthesis of the diacetal trioxa-cage compounds 9 and 10 with alkene group or carbonyl group on the apex carbon have been accomplished from ozonolysis of diol compounds 4.
Reaction of the trioxa-cages 9 and 10 with electrophiles and nucleophiles exclusively gave the corresponding anti-attack products.
The synthesis of the diacetal trioxa-cage compounds 23 and 26 have been accomplished from ozonolysis of diol compounds 22 and 25.
Reaction of 23 and 26 with TiCl4 in dichloromethane gave the hydride rearrangement products 29 and 30.
Reaction of 23 and 26 with Lawesson's Reagent in dichloromethane gave the transformation products 32 and 33.
Ozonolysis of diols then adding n-butylamine gave the diacetal dioxamonoaza-cages 34 and 35.
