Abstract

A general procedure for the synthesis of diverse cyclopentanols via free-radical cyclization of unsaturated 1, 3-oxathiolanes and 1, 3-oxathiolan-5-ones is described. The scope of these reactions, including preliminary rate studies that indicate that the 1, 3-oxathiolan-5- ones cyclize at a useful rate (1.4× 106 M-1 s-1 at 80° C), has been examined. This permits the rapid assembly, by intramolecular annulation, of various additional ring systems, ...
