title: SYNTHESIS AND REACTIVITY OF ENAMINONE OF NAPHTHO[B] 1,4-OXAZINE: ONE POT SYNTHESIS OF NOVEL ISOLATED AND HETEROCYCLE-FUSED DERIVATIVES WITH ANTIMICROBIAL AND ANTIFUNGAL ACTIVITIES.
abstract: The synthesis of the multifunctional, hitherto unreported 3-(3-(dimethylamino)acryloyl)-2H-naphtho[1,2- b] [1,4]oxazin-2-one was described and its utility as a versatile building block was demonstrated for the synthesis of some new pyrimidines, pyrazoles, isoxazoles, pyrazolo[a]pyrimidines, triazolo[a]pyrimidines, pyrido[d]pyrimidines, pyrido[d]pyrimidines, piperidines, pyrido[a]benzimidazoles, 2H-pyran-3-carboxamides, benzofurans, naphtho[b]furans and pyrazolo[c] [1,2,4]triazines of potential biological activities. The synthesized compounds were characterized by IR, 1H NMR, 13C NHR and mass spectral data. Some of the compounds were evaluated for antimicrobial activities.
