- The first total synthesis of viscumneoside III, a promising anti-angina pectoris dihydroflavone O-glycoside isolated from Viscum coloratum was described here. Trichloroaceti-midate was employed as the apiofuranosyl donor to construct the key building block of homoeriodictyol-7-O-β-d-apiosyl-(1 → 2)-β-D-glycoside (1). The longest linear sequence (from 2 to 1) in the synthetic route required thirteen steps and afforded the final product 1 with an overall yield of 6.3%.
