, p. 1149 - 1154 (2007)
A series of 5-arylidene-2,4-thiazolidinediones and its geranyloxy or prenyloxy derivative were synthesized and studied for their radical scavenging activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Their comparable scavenging activities were expr

A series of 29 oxyprenylated and azoprenylated phenylpropanoids were chemically synthesized and tested in transfected cultured HepG2 cells by means of the dual-luciferase assay as farnesoid X receptor (FXR) agonists, using the endogenous ligand chenodeoxy
Convenient synthesis of (E)-methyl O-alkylferulates: Formal synthesis of O-geranylconiferyl alcohol, a metabolite of Fagara rhetza

A convenient two step stereoselective synthesis of (E)-methyl O-alkylferulate 5a-c is described from vanillin 1. Reaction of vanillin 1 with allyl-, prenyl- or geranyl- bromide 2a-c has afforded alkyl ethers 3a-c which on reaction with phosphorane 4, under microwave irradiation, gives (E)-methyl O-alkylferulates 5a-c in high yield. In an alternative approach vanillin 1 on reaction with phosphorane 4 provides (E)-methyl ferulate 6 which on reaction with the corresponding bromides 2a-c gives (E)-methyl O-alkylferulates 5a-c.
