Four methyl-substituted cyclopentanones were reacted with lithium aluminum hydride in tetrahydrofurap and with meth, yllithium in ether at 0" C. In general, secondary trans alcohols were formed preferentially with lithium aluminum hydride, while tertiary cis alcohols were obtained as the major product with methyllithium. In 2, 5-dimethyl-and 2, 2, 5- trimethylcyclopentanones, the original preference of the cis alcohols was reversed when ...
