This report describes a simple two-phase process for the oxidation of benzo[b]thiophene, the generation of aromatic nitriloxides, the cycloaddition of the latter with the oxidized benzo[b]thiophene and the halogenation of the cycloadducts. All these reactions can be effected in a one-pot procedure.

- NOUVELLE METHODE DE SYNTHESE DES 4,5-DIHYDROISOXAZOLES EN MILIEU BIPHASIQUE SOLIDE-LIQUIDE ET PAR ACTIVATION ULTRASONIQUE
-
A novel methodology is developed for a 'one-pot' synthesis of 4,5-dihydroisoxazoles. 1-Sodio 3,5-dichloro-s-triazine-2,4,6-trione, alumina, dichloromethane, arylaldoximes, dipolarophiles and ultrasound irradiation are the leading ingredients in the succes
