Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , HPLC of Formula: C19H15NO5, 82911-69-1, Name is N-(9-Fluorenylmethoxycarbonyloxy)succinimide, molecular formula is C19H15NO5, belongs to thiazines compound. In a document, author is Salah, Hanan, introduce the new discover.
Ring rearrangements and reactivity of 3-((4-oxo-4H-chromen-3-yl)methylene)-4-phenyl-1H-[1,5]benzodiazepin-2(3H)-one toward some nucleophiles
Condensation of 4-phenyl-1H-[1,5]benzodiazepin-2(3H)-one (1) with 3-formylchromone (2) afforded a mixture of 3-(chromenylmethylene)[1,5]benzodiazepinone 3 and 14-chromenyl-benzodiazepino[2,3: 6,5] pyrano[2,3-b] benzodiazepine 4. Ring rearrangements of compound 3 with different nucleophilic reagents, such as potassium hydroxide and/or ammonium acetate led to rearrangement into pyranobenzodiazepine 5 and pyridobenzodiazepine 6, respectively. Treatment of compound 3 with hydrazine hydrate, hydroxylamine hydrochloride, malononitrile, cyanothioacetamide, 2-cyano-3,3-disufanylacrylonitrile, and/or 2-cyano-3-phenylamino-3-sufanylacrylonitrile, has been carried out at different conditions, leading to versatile heterocyclic substituted benzodiazepines at position 3, viz. pyrazole 8, isoxazole 9, pyridines 10 and 11, 1,3-dithiine 12, and 1,3-thiazine 13 derivatives.
