The anti/syn stereoselectivity in the metal hydride reductions of a series of substituted 3,4-dihydro-1,4-ethanonaphthalen-2(1H)-ones was studied. The observed steroselectivity sequence was found to be parallel with the homoconjugation sequence except for the case of 5,8-dimethoxy-substituted derivative: the portion of anti attack increases as the benzene ring becomes electron-rich. The results were
