Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 6106-21-4, Name is Sodium succinate hexahydrate, molecular formula is C4H16Na2O10, belongs to benzisoxazole compound, is a common compound. In a patnet, author is JOSHI, KC, once mentioned the new application about 6106-21-4, Recommanded Product: 6106-21-4.
STUDIES IN SPIROHETEROCYCLES .26. INVESTIGATION OF THE REACTION OF 3-(2-OXOCYCLOALKYLIDENE)INDOL-2(1H)-ONES WITH HYDROXYLAMINE HYDROCHLORIDE AND PHENYLSULFONYL HYDRAZIDE
Reactions of fluorinated 3-(2-oxocycloalkylidene)indol-3(1H)-ones (1) with 4-fluorophenylsulphonyl hydrazide in ethanolic KOH yielded spiro[3H-indazole-3,3′(3H)-indole]-2′(1’H)-ones (2a, b; n = 2) and spiro[3H-indole-3,3′(3H)-pyrazol]-2(1H)-ones (2c; n = 1). Further, the reaction of 1 with hydroxylamine hydrochloride in dry pyridine in the presence of fused sodium acetate yielded some new 2,3a,4,5,6,7-hexahydro[spiro-3H-benzisoxazole-3,3′(3H)-indol]-2′(1’H)-ones (3a, b; n = 2) and 4′,5′-cyclopentaspiro[3H-indole-3,3′(3H)-isoxaazol]-2(1H)-ones (3c, d; n = 1). The nonfluorinated analog gave 3-(2-oxocycloalkylidene)-2′-oximeindole-2(1H)-one (4a) in addition to the spiro compound (3a). All the compounds have been characterised from their analytical and ir, pmr, C-13 nmr, F-19 nmr and mass spectral data.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 6106-21-4. The above is the message from the blog manager. Recommanded Product: 6106-21-4.
