Dichloroketene adds onto the face of the carbonyl group of 7-oxabicyclo [2.2.1] hept-5-en-2-one to yield a dichloro- β -lactone with complete chemo- and stereoselectivity. This dichlorolactonization has been extended to other oxanorbornenic systems and the resulting β-lactones were transformed into the corresponding 1,3-diols.
