Abstract

S~~ m~~ aary. The aprotic decomposition of 5-amino-3, 4-dinicthyl-isoxazole with excess isoaniyl nitrite in aromatic solvents (alkylbcnzenes, polyalkylbenze, ncs, anisole efc.) and in hetcroaromatic solvents (thiophcnc, 2, 4-diinethylthiazole. pyridine, 4-alliylpyridincs, dimethyl-and trimethylpyridines) leads to 5-aryl-and 5-hcteroaryl-isoxazolcs in yields of about 40%. This nicthod provides a new way of obtaining 5-iodo-3, 4-dimctIiyl-isoxazole ...
