    A tetrasaccharide, dodecanyl 4-O-acetyl-alpha-L-rhamnopyranosyl-(1 -> 3)-2,4-di-O-acetyl-alpha-L-rhamnopyranosyl-(1 -> 3)-4-O-acetyl-alpha-L-rhamnopyranosyl-(1 -> 4)-alpha-L-rhamnopyranoside (cleistetroside-2), was synthesized via '2+2' convergent strategy. Sequential regioselective 3-O-glycosylation of isopropyl 1-thio-alpha-L-rhamnopyranoside (4) with 4-O-acetyl-2,3-O-isopropylidene-alpha-L-rhamnopyranosyl trichloroacetimidate (8), and isopropyl 4-O-acetyl-2,3-O-isopropylidene-alpha-L-rhamnopyranosyl-(1 -> 3)-2,4-di-O-acetyl-alpha-L-1-thio-rh amnopyranoside (10) with dodecanyl 4-O-acetyl-alpha-L-rhamnopyranosyl-(1 -> 4)-2,3-O-isopropylidene-alpha-L-rharnnopyranoside (12), greatly facilitate the target availability.

  • Synthesis of Several Cleistrioside and Cleistetroside Natural Products via a Divergent De Novo Asymmetric Approach
    作者:Bulan Wu、Miaosheng Li、George A. O’Doherty
    DOI:10.1021/ol1023344
    日期:2010.12.3
    The de novo asymmetric syntheses of several partially acylated dodecanyl tri- and tetra-rhamnoside natural products (cleistriosides-5 and 6 and cleistetrosides-2 to 7) have been achieved (19−24 steps). The divergent route requires the use of three or less protecting groups. The asymmetry was derived via Noyori reduction of an acylfuran. The rhamno-stereochemistry was installed by a diastereoselective
