Formula: C9H10O3. I found the field of Chemistry very interesting. Saw the article Tetrabutylammonium-Bromide-Promoted Synthesis of Spirooxindoles through Alkyne-Aldehyde C-C Coupling and 1,3-Dipolar Cycloaddition Using Ytterbium Triflate Catalyst published in 2020.0, Reprint Addresses Khan, FRN (corresponding author), Vellore Inst Technol, Sch Adv Sci, Organ & Med Chem Res Lab, Vellore 632014, Tamil Nadu, India.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde.
Tetrabutylammonium-bromide promoted, ytterbium triflate catalyzed one-pot domino synthesis of spirooxindoles is described. The hydration-condensation of alkyne,1aldehyde,2C-C coupling followed by 1,3-dipolar cycloaddition of in-situ generated azomethine ylide from Isatin,3and L-proline,4 aor sarcosine,4 bfurnished novel spirooxindoles,5under solvent-free green-chemical conditions, in high regio and stereo selectivities and yields. The regio and stereochemistry of the synthesized derivatives were characterized by 2D NMR Spectroscopic studies.
Formula: C9H10O3. About 2,5-Dimethoxybenzaldehyde, If you have any questions, you can contact Teja, C; Khan, FRN or concate me.
