Résumé
Beta-[2,4,6-trimethyibenzoyl]- acryloyl chloride reacts with anthranilic acid to give [1] which is easily cyclized by the action of acetic anhydride to give the Benzoxazone[2]. Condensation of [2] with hydrazine hydrate give [3]. The behaviour of [3] towards the action of aromatic aldehydes, ketones, phthalic anhydride and phthalyl amino acid chlorides has been investigated. Reactions of [2] with o-phenylene diamine, ammonia, grignard reagents, friedl-crafts reaction and bomine has been described
