MONOTERPENOID AND PHENYLETHANOID GLYCOSIDES FROM LIGUSTRUM PEDUNCULARE
Two new phenylethanoid glycosides, lipedosides A-I and A-II as well six new monoterpene glycosides, lipedosides B-I-B-IV were isolated together with three known constituents, osmanthuside B, anatolioside and linalool from Ligustrum pedunculare.Their structures have been elucidated by chemical and spectroscopic methods.
Collective syntheses of phenylethanoid glycosides by interrupted Pummerer reaction mediated glycosylations
The collective total syntheses of nine natural phenylethanoid glycosides (PhEGs) together with proposed Incanoside B in a divergent mode were described. By using a core disaccharide as common intermediate, our developed interrupted Pummerer reaction media
Verbascoside and Isoverbascoside from Paulownia Tomentosa Steud
The structure of verbascoside and isoverbascoside, isolated from the leaves of Paulownia tomentosa Steud. have been determined by NMR spectroscopy and partially hydrolysis to be β-(3,4-dihydroxyphenyl)ethyl-O-α-1-rhamnosyl(1-->3)-β-D-(4-O-caffeoyl)-glucopyranoside (1) and β-(3,4-dihydroxyphenyl)ethyl-O-α-L-rhamnosyl(1-->3)-β-D-(6-O-caffeoyl)-glucopyranoside (2). - Key words: Paulownia tomentosa Steud., Caffeoylglycoside, Verbascoside
