Abstract
A mild method for the preparation of 1,3-dithianes from aldehydes and keton es is described. By using lithium perchlorate as Lewis acid and propane-1,3 -dithiol even highly acid-labile beta-hydroxy aldehydes can be transformed into the corresponding thioacetals. The desired products were obtained in 4 1-98% yield.
