5-Oxazolones. Part V. Reaction of 4-alkylidene-5(4H)-oxazolones with ethyl 3-oxo-4-triphenylphosphoranylidene-butyrate / F. Clerici, E. Folpini, M.L. Gelmi, D. Pocar. - In: TETRAHEDRON. - ISSN 0040-4020. - 47:42(1991), pp. 8907-8916.
Abstract:
The reaction of 4-alkylidene-5(4H)-oxazolones 2a-e with ethyl 3-oxo-4-triphenylphosphoranylidene-butyrate 1 affords dihydrobenzoxazoles 3a-c and the diastereoisomeric 1,3-cyclohexanedione ylides 4a-e and 5a-e. 3a is oxidized to the corresponding benzoxazoles 7a,b with iodine.
