Intramolecular Diels-Alder reactions of cyclobutenone and larger cycloalkenones are described. High levels of endo addition attained from Lewis acid catalysis translate to trans hydrindene junctions upon fragmentation of the tricyclic adducts.
本文描述了环丁烯酮和更大环烯烃酮的分子内环 Diels-Alder 反应。路易斯酸催化下获得的高比例内加成物,在三环状加成物断裂时转化为反式氢化茚键结。
