  Total synthesis of fuzinoside

  摘要：

  The first total syntheses of fuzinoside (1b) were achieved from o-galactose through two strategies (BCA and ABC) in 11 (total yield: 5.0%) and 15 (total yield: 3.7%) steps, respectively. Comparison of NMR data of synthetic compound 1b and those of the fuzinoside isolated from the lateral roots of Aconitum carmicaelii suggests that the structure reported in the literature(1,2) might not be accurate. The synthetic fuzinoside (1b) exhibited moderate cardiac activity in the isolated bullfrog heart assay. (C) 2014 Elsevier Ltd. All rights reserved.
