Abstract:	Glycals react rapidly with polymethylhydrosiloxane (PMHS) in the presence of a catalytic amount of molecular iodine under mild conditions to afford the corresponding 3,6-dihydropyran derivatives in excellent yields. Et₃SiH/I₂ was also found to be effective for this conversion.

Keywords:	Glycals Molecular iodine PMHS Dihydropyrans
