Article abstract of DOI:10.1016/S0040-4020(01)89305-4

A new sequential carbonyl-ene cyclization/cycloalkylation of trifluoromethyl ketones catalyzed by aluminum Lewis acids is described. From ketone 1, the 4-CF₃-4-OH cis-octahydrophenanthrene 6 is obtained in 50% yield. From ketone 2, with MeAlCl<
