In present study, a novel class of 3,7-disubstituted 2H-1-benzopyran-2-one derivatives (3xa-3zc) bearing a basic ether side chain at C-7 and a substituted phenyl ring at C-3 of the coumarin ring is synthesized. These compounds have been evaluated for anti

A simple and environmentally friendly strategy for the synthesis of E-ortho-hydroxystilbenes has been established. Two kinds of α,β-unsaturated aromatic lactones, i.e. the 3-arylcoumarins and the isoaurones, could both readily undergo a cascade hydrolyzation/decarboxylation reaction in the presence of KOH in ethylene glycol to afford the desired E-ortho-hydroxystilbenes in moderate to high yields.
Hydroxyl substitutional effect on selective synthesis of CIS, trans stilbenes and 3-arylcoumarins through perkin condensation
Xiao, Chun-Fen,Zou, Yong,Du, Jian-Li,Sun, Hong-Yi,Liu, Xian-Ke
experimental part, p. 1243 - 1258 (2012/04/04)
The substitutional effect in the selective synthesis of cis, trans stilbenes and 3-arylcoumarins has been described. The regio- and geometrical selectivity for synthesis of stilbene derivatives under the Perkin strategy strongly depends on the presence or absence of hydroxyl group as well as their positions in the phenyl ring. As a result, practical synthetic strategies were established for preparing various natural stilbenes including combretastatin A-4, pterostilbene, and resveratrol with satisfactory yields (49.2-63.7%).
