An article Facile Access to 3,4-Disubstituted 2H-Chromenes via Domino [4+2] Annulation WOS:000590476800003 published article about ORTHO-QUINONE METHIDES; ONE-POT; CHROMENES in [Kim, Ikyon] Yonsei Univ, Coll Pharm, 85 Songdogwahak Ro, Incheon 21983, South Korea; Yonsei Univ, Yonsei Inst Pharmaceut Sci, 85 Songdogwahak Ro, Incheon 21983, South Korea in 2021, Cited 28. The Name is Mequinol. Through research, I have a further understanding and discovery of 150-76-5. HPLC of Formula: C7H8O2
A highly efficient synthetic route to polysubstituted 2H-chromenes was developed utilizing a domino O-alkylation/intramolecular Horner-Wadsworth-Emmons (HWE) olefination of diarylmethylphosphonates, which were readily accessed via Lewis acid mediated one-pot three-component coupling of aldehydes, phenols, and triethyl phosphite.
HPLC of Formula: C7H8O2. About Mequinol, If you have any questions, you can contact Prasad, SS; Joshi, DR; Kim, I or concate me.
