Abstract
A Davis–Beirut reaction inspired nitroso Diels–Alder protocol is reported. The starting material for the procedure is a nitrophenyl moiety with the para position appropriately substituted with a 2°-amine (see 5) or 2°-alcohol (see 6). Deprotonation at the benzylic position followed by concomitant oxidation of the benzylic position and reduction of the nitro moiety delivers a nitrosophenyl intermediate, which subsequently undergoes a nitroso Diels–Alder reaction. This one-pot procedure delivers aryldihydro-1,2-oxazines in moderate yields.
