Sharpless epoxidation of 4-amino-3-methyl-5-styrylisoxazoles 1 resulted in the formation of 3-methyl-5-aryl-4H-pyrrolo[2,3-d]-isoxazoles 4 in a one-step reaction. The reaction initially involves epoxide formation, followed by ring-opening and cyclization. Finally dehydration leads to the title compounds. The pyrrolo[2,3-d]-isoxazoles 4 were also synthesized via an alternative procedure. (c) 2006 Published by Elsevier Ltd.
