Thioisomünchnones undergo 1,3-dipolar cycloaddition with chiral nitroalkenes to afford stereoselectively 4,5-dihydrothiophenes by means of an unprecedented fragmentation of cycloadducts; the structures of these products have been established by single crystal X-ray structure analyses.
硫代异马钱子酮与手性硝基烯发生 1,3 双极环加成反应,通过环加成产物前所未有的碎片化,立体选择性地得到 4,5- 二氢
噻吩;这些产物的结构已通过单晶 X 射线结构分析得以确定。
