摘要：

A copper(II) exchanged cation exchange resin has been used as support for reduction of ketones with sodium borohydride. Supported Cu(II) ions activate the reduction of ketones to a large extent and control the stereochemistry of reductions of cyclic ketones resulting in preponderance of equatorial alcohol in most cases.
