title: Efficient cleavage of the N-O bond of 3,6-dihydro-1,2-oxazines mediated by some alpha-hetero substituted carbonyl compounds in mild conditions.
abstract: The efficient cleavage of the N-O bond of some nitroso Diels-Alder cycloadducts has been achieved in mild conditions, mediated either by 2,2-dimethyl-1,3-dioxan-5-one or 1,3-dithiolane-2-carboxaldehyde. These new and purely organic conditions allow an excellent tolerance with respect to many functional groups that would have been affected by previous reductive cleavage conditions.
