Thermal Rearrangement of some Oxazolidine N-Oxides. 2-Alkyl-6-aryl-3,4-dihydro-2H-1,5,2-dioxazines

Saba, Shahrokh,Domkowski, Patrick W.,Firooznia, Fariborz

, p. 921 - 923 (2007/10/02)

3-Alkyl-2-aryloxazolidines are oxidized with 3-chloroperoxybenzoic acid to produce the corresponding oxazolidine N-oxides.These N-oxides undergo thermal rearrangement to give 2-alkyl-6-aryl-3,4-dihydro-2H-1,5,2-dioxazines in 55-85 percent yield.
