Electrochemical reduction of the title compound (1) in nonaqueous solvent results in intramolecular displacement of the mesyloxy group to give the tricyclic ketone (2). The implications for the mechanism of organo-cuprate reactions are discussed.

Some Observations on the Mechanism of Diorganocuprate 1,4-Addition Reactions with α,β-Unsaturated Ketones: Effects of Diethyl Ether in Reactions of Butylcoppers in Toluene

Mixtures of butyllithium and copper iodide prepared in toluene react with alpha,beta-unsaturated ketones predominantly in a 1,2-fashion. Addition of 2 equiv of diethyl ether to the system results in a dramatic preference for the 1,4-product, as found normally with diorganocuprates in ethereal solvents. These results are in accordance with the theoretical predictions that a suitable ligand is required to facilitate the stabilization of a formally copper(III) reaction intermediate on the 1,4-addition mechanistic pathway.
