Study on the Medium Effect to the Diels-Alder Reaction of γ-Oxo-α,β-Unsaturatewd Thioester with Cyclopentadiene. Synthesis of Oxa-Cages which Contain Two and Three Oxygen Atoms on the Skeleton
博士 === 國立交通大學 === 應用化學研究所 === 84 === Diels-Alder reaction of the cis-isomer 2b with cyclopentadiene in various media are investigated. In β-CD aqueous solution, the endo/exo ratio can be increased up to 99:1. Diels-Alder reaction of the trans-isomer 3 with cyclopentadiene gave the cycloadducts...
