The reaction of cyclic nitronic esters (isoxazoline- and 5,6-dihydro-4H-1,2-oxazine-N-oxides) with hydrochloric acid affords geminal chloronitroso compounds bearing a distant hydroxyl group. The reaction is usually diastereoselective, and in some cases stereodivergent formation of isomers at different temperatures is observed. The discovered process represents the first example of an interrupted Nef
