General description

Geranyl bromide undergoes palladium catalyzed cross-coupling reaction with aryl and alkenylgold(I) phosphanes.

Application

Geranyl bromide was used in synthesis of baicalein and 3,7-dihydroxyflavone derivatives. It was also used in synthesis of potential flavonoidic modulators of P-glycoprotein activity.

A new series of potential flavonoidic modulators of P-glycoprotein activity has been prepared. The flavanolignan silybin was first oxidised to dehydrosilybin and then C-alkylated with either prenyl or geranyl bromide. The resulting isoprenoid dehydrosilybins were shown to display high in

Fourteen baicalein and 3,7-dihydroxyflavone derivatives were synthesized and evaluated for their inhibitory activity against the in vitro growth of three human tumor cell lines. The synthetic approaches were based on the reaction with prenyl or geranyl bromide in alkaline medium
