摘要

We report the first total synthesis of 3, 5-O-dicaffeoylquinic acid and its derivatives, 3, 5-O- diferuloylquinic acid and 3, 5-(3, 4-dimethoxycinnamyl) quinic acid, in a nine-step sequence. The key step involves Knoevenagel condensations between vanillin, 3, 4- dimethoxybenzaldehyde or 4-hydroxy-3-methoxybenzaldehyde and the dimalonate ester of quinic acid.
