Acyclic stereocontrol of free radical reactions involving alkyl 2-(1-hydroxyalkyl)propenoates
Eastwood,Mifsud,Perlmutter
, p. 2187 - 2200 (2007/10/02)
The addition of cyclohexyl and t-butyl free radicals to silylated derivatives of alkyl 2-(1-hydroxyalkyl)propenoates was found to be stereoselective. In the case of the cyclohexyl radical the stereoselectivity was dependent upon the conditions used to gen
