摘要
Here we demonstrate that N-(2,3,4,5,6-pentafluorophenyl)maleimide effectively promotes dearomatizing Diels-Alder reactions of 2,5-dimethylbenzene-1,4-diol and naphthalen-2-ol derivatives. The present reactions successfully converted the sp(2)-rich components to the desired products with multiple sp(3)-carbons in a single step. The adduct was further derivatized into the intermediate for our synthesis of 9-demethy1-10,15-dideoxyryanodol, an analogue of a sp(3)-rich natural product, in two steps.
