Total syntheses of schizandriside, saracoside and (±)-isolariciresinol with antioxidant activities

Lignans are widely distributed in plants and exhibit significant pharmacological effects, including anti-tumor and antioxidative activities. Here, we describe the total synthesis of schizandriside (1), a compound we previously isolated from Saraca asoca b

Synthesis of L-Alanyl-3-O-(β-D-xylopyranosyl)-L-seryl-glycyl-L-isoleucine. Direct Glycosydation of Peptides

Glycosidation of the tetrapeptide 8 either with 1,2,3,4-tetra-O-acetyl-β-D-xylopyranose (1) under catalysis of trimethylsilyl triflate or with ethyl 2,3,4-tri-O-benzoyl-1-thio-β-D-xylopyranoside (4) using DMTST as promotor, leads to the O-glycopeptides 10 and 9.Deblocking of 10 affords the glycopeptide L-Ala-3-O-(β-D-Xylp)-L-Ser-Gly-L-Ile (11), which represents the N-terminal amino acid sequence 3 to 6 of the protein core of a proteodermantan sulfate.
