Lewis acids catalyzed ring-opening reactions of methylenecyclopropanes and epoxides in supercritical carbon dioxide or modified supercritical carbon dioxide with perfluorocarbon
摘要:
The reactions of methylenecyclopropanes (MCPs) and epoxides with alcohols and aromatic amines can be carried out in supercritical carbon dioxide (scCO(2)) or modified scCO(2) with perfluorocarbon which offer a way to synthesize various alcohols, amino-alcohols, homoallylic ethers, and amines under an environmentally benign condition.

Methylenecyclopropanes (MCPs) can react with aromatic amines to give the corresponding homoallylic amines in good to high yields in the presence of Lewisacids. The substituents on the benzene ring of the MCPs or the aromatic amines can affect significantly the reaction rate.
