Precomplexation of 2-butylcyclopentanone with methylaluminum bis(2,6-di-hrt-butyI-4-methylphenoxide) (MAD), prior to the addition of methyllithium, leads to the exclusive formation of the equatorial alcohol via cis attack3 4. However, this methodology is apparently not applicable to 3-substituted cyclopentanones. Thus, addition of propylmagnesium bromide to...
