HF–pyridine promoted Friedel–Crafts type arylation of 2-acetoxy-d-glucal. Stereoselective synthesis of 1-arylhex-3-enopyranosiduloses
Abstract
A variety of aromatic substrates were treated with 2-acetoxy-D-glucal in the presence of HF–pyridine to give 1-arylhex-3-enopyranosiduloses in high yield and in high α-selectivity.
