Lespedezavirgatol, a novel 2-phenylbenzofuran compound which was isolated from Lespedeza virgata, was firstly synthesized from pyrogallic acid and 3,4-dimethoxyphenol as starting materials with 8 steps. The key steps for the total synthesis were the selective iodination at 3-position of 1,2-dimethoxy-4-methoxymethoxybenzene and the Sonogashira cross-coupling reaction between 4-iodo-2-methoxybenzene-1,3-diol and 2-ethynyl-3,4-dimethoxy-1-(methoxy-methoxy)-benzene.
