10-Aryl-3a,4,10,10a-tetrahydrofuro[3,4-b]carbazol-1-ones were synthesized by an intramolecular Diels-Alder reaction. Exo/endo product ratios were found to be sensitive to both solvent and temperature. The synthesis of isoelliptitoxin 2, a hybrid molecule of ellipticine and 4'-demethylpodophyllotoxin, is presented.
通过分子内Diels-Alder反应合成了10-芳基-3a,4,10,10a-四氢呋喃[3,4-b]咔唑-1-酮。发现外/内产物的比率对溶剂和温度均敏感。介绍了玫瑰树碱和4'-去甲基鬼臼毒素的杂合分子异椭圆毒素2的合成。
