Synthesis of a New Phenol Glycoside, Neohancoside C from Cynanchum hancockianum.-The synthesis of a new phenol glycoside (V) is presented, key step being the phase-transfer catalyzed glycosylation of acetophenone (III) with glucose derivative (II). The best protecting group for the regioselective introduction of the xylose unit proved to be the acetyl group. -(KONDA, Y.; IWASAKI, Y.; TAKAHATA, S.; ARIMA, S.; TOIDA, T.; KAJI, E.; TAKEDA, K.; HARIGAYA, Y.; Chem.
