Asymmetric induction. An anisotropic inductive effect as an important factor in the hydride reduction of 3-alkyl bicyclo[2.2.2]octan-2-ones
Abstract
The unexpectedly large proportions of trans alcohols (5) formed in the title reaction, especially when R = Pri, and the trends in the rate constants, are attributed to an anisotropic inductive effect of the alkyl groups, which leads to an anomalously high rate of attacks from the allkyl side of the carbonyl group.
