A Systematic Study of the Hydride Reduction of Cyclopropyl Ketones with Structurally Simplified Substrates. Highly Stereoselective Reductions of <i>Trans</i>-Substituted Cyclopropyl Ketones via the Bisected <i>s</i>-<i>Cis</i> Conformation
stereoselective hydride reduction of the cis- and trans-substituted cyclopropylketones was systematically investigated using a series of structurally simplified substrates, trans-[tert-butyldiphenylsilyloxymethyl]cyclopropylketones 1a-e and trans-(benzyloxymethyl)cyclopropylmethylketone (2), and the corresponding cis congeners 3a,b,e and 4. The results showed that, not only in the reduction of the cis-substituted
