Abstract

[GRAPHICS]This study represents the first examples of stereoselective radical cyclizations on soluble supports. A stereocontrol element consisting of a polymer-imbedded (+)-isosorbide chiral auxiliary was used in each monomer subunit. A survey of various Lewis acids was also examined. The best results gave very high distereoselectivites of > 100:1 in a hepa-1,3-dienenyl radical cyclization using zinc chloride as a Lewis acid.
