Abstract

Myricetin-3-O-β-d-glucuronide, a bioactive flavonol glycoside, was synthesized effectively starting from myricetrin in a total yield of 49.2%. The structures of all synthetic compounds were confirmed by 1H, 13C NMR, and HR-MS techniques. [ABSTRACT FROM AUTHOR]

Abstract

The first total synthesis of 6′-hydroxyjusticidin A, isolated from Justicia procumbens L. with good inhibitory activity against cancer cells, has been accomplished. The structure was confirmed by 1H NMR, 13C NMR, and HR-ESI-MS. The key steps involved a Diels–Alder cycloaddition reaction and a reduction in NaBH4. [ABSTRACT FROM AUTHOR]
