Abstract

The 4,6-O-cyclopropylmethylidene (CPMD) moiety of a methyl α-glucoside derivative can be regioselectively opened by trimethylaluminum to afford a corresponding 1-cyclopropylethyl (CPE) ether at C4 and a free alcohol at C6. This 1-CPE ether was found to be an acid-labile hydroxyl protecting group and can be readily cleaved using 10% trifluoracetic acid in dichloromethane at room temperature. The utilization of 1-CPE ether as a hydroxyl protecting group has been demonstrated in the efficient synthesis of a trisaccharide.

期刊介绍: The Journal of Carbohydrate Chemistry serves as an international forum for research advances involving the chemistry and biology of carbohydrates. The following aspects are considered to fall within the scope of this journal: -novel synthetic methods involving carbohydrates, oligosaccharides, and glycoconjugates- the use of chemical methods to address aspects of glycobiology- spectroscopic and crystallographic structure studies of carbohydrates- computational and molecular modeling studies- physicochemical studies involving carbohydrates and the chemistry and biochemistry of carbohydrate polymers.
