Abstract

Oxidative cyclization of 1, 5-dienes in acetic acid and in the presence of the Pd (I1) regenerating catalyst system Pd (OAc) 2/Mn02/p-benzoquinone has been shown to yield, depending on the structure of the 1, 5-diene, acetoxyexomethylenecyclopentanes or acetoxyvinylcyclopentanes. 1, 5-Dienes with substitutents in the 1-and/or 3-position show a high preference for formation of regioisomers obtained by acetate attack at the sterically ...
