Stereochemistry of the Reductive Alkylation of α,β-Epoxy Ketones
McChesney, James D.,Thompson, Thomas N.
, p. 3473 - 3481 (2007/10/02)
α-Epoxy ketones have been found to be useful intermediates for regiospecific alkylation of ketones.We have examined the steric course of the alkylation and shown it to be highly stereoselective.
