Design, Synthesis, Characterization, and Crystallographic Behaviors of Some Biologically Important Chromene-Annulated Spiro-Oxindoles: A Drive to Introspect the Comparative Structural Information
The compounds, 2-amino-2′,5-dioxo-5,6,7,8-tetrahydrospiro[chromene-4,3′-indoline]-3-carbonitrile (4a), 2-amino-1′-methyl-2′,5-dioxo-5,6,7,8-tetrahydrospiro[chromene-4,3′-indoline]-3-carbonitrile (4b), and 2-amino-1′,7,7-trimethyl-2′,5-dioxo-5,6,7,8-tetrahydrospiro[chromene-4,3′-indoline]-3-carbonitrile (4c) were synthesized and characterized by elemental analyses, spectral studies (FT-IR, NMR, Mass) and single-crystal X-ray analysis. All the compounds crystallize in the monoclinic sp. gr. P2(1)/c. In crystals of all three compounds, the molecules are linked by an elaborate system of N-H…O and N-H…N hydrogen bonds to form supramolecular structures.
Reference of 87-48-9, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 87-48-9.
