A known one-pot procedure for the synthesis of 2-(phenylselanyl)tetrahydrofurans could be applied to the transformation of γ-lactones 3a-c into 2-(phenylselanyl)tetrahydrofurans 1a-c. Surprisingly, formation of γ-hydroxydiselenoacetals 5b and 5c was observed when γ-lactols 4b and 4c were treated with selenophenol and boron trifluoride etherate.
