Syntheses of 3-, 4- and 5-O-Feruloylquinic Acids

Efficient synthesis of 3-, 4- and 5-O- feruloylquinic acids starting from D-(-)-quinic acid is described. Esterification of suitably protected quinic acid derivatives with 3-(4- acetoxy-3-methoxyphenyl)-acryloyl chloride and subsequent hydrolysis of all protecting groups afforded title products in overall yield of 33%, 15% and 45% respectively (from quinic acid).
