| Summary: | 碩士 === 國立交通大學 === 應用化學系 === 91 === We systemically further discuss Diels-Alder reaction adducts (7-9) from pyranone derivatives and cyclopentadiene undergo iodolactonization , the stereoselective in this reaction is very high .
Because the stereoselective is very high in the reaction which adducts (7-9) undergo iodolactonization , further we want to discuss compound (7-9) derivatives, as compound (25、26), which stereoselective is high or not in iodolactonization .
Discuss the Diels-Alder reaction when Lewis acid present .
