摘要：

4-Dimethylaminopyridine-N-oxide 2 and 2',3',5'-triacetyladenosine-N-1-oxide 4 are partially deoxygenated by dimethyldioxirane (DMD) to the corresponding amines 1 and 3; the formation of singlet oxygen suggests a polar rather than a radical mechanism, in which we propose S(N)2 attack of the N-oxide on the dioxirane peroxide bond.
