A Highly Efficient Synthesis of Tri-O-Acyl-α-D-Glucopyranose 1,2-(Orthoesters) under High Pressure
High pressure-assisted condensation reaction of acylated glucosyl bromides with complex alcohols in the presence of diisopropylethylamine and tetrabutylammonium bromide gave the corresponding 1,2-orthoesters in good to excellent yields without using heavy
