Treatment of methyl 2-C-formylmethyl-2-deoxy-β-D-glucopyranoside (5) or methyl 2-C-acetylmethyl-2-deoxy-β-D-glucopyranoside (1) with H2SO4–HOAc–Ac2O gave 2-acetoxyl-4,5-bis(benzyloxy)-6-[(benzyloxy)methyl]hexahydrofuro[2,3-b]pyran (6) and acetyl 2-C-acetylmethyl-2-deoxy-α-D-glucopyranoside (7) respectively, which were further reacted with nucleophiles in(More)
A rearrangement reaction of 1,2-cyclopropanated sugars with alkylamines or arylamines promoted by Zn(OTf)2 is described. The method offers a series of 3-polyhydroxyalkyl-substituted pyrrole derivatives with multiple chiral centers in moderate to excellent yields. The epimerization is achieved by inverting the stereochemistry at the free hydroxyl group of(More)
In this letter we describe a simple physical method for the ordered aggregation of scattered single spherical polystyrene-b-poly(acrylic acid) (PS-b-PAA) micelles. First, narrow dispersed spindlelike aggregates, about 60 nm in diameter and 1.5 microm in length, are obtained from the aggregation of single spherical PS-b-PAA micelles at 0 degrees C on a glass(More)
