摘要：

The installation of the 2-furyl ring at the anomeric carbon of 2,3,4,6-tetra-O-benzyl-D-glucopyranose and 2,3.5,6-di-O-isopropylidene-D-mannofuranose is carried out either by addition of 2-lithiofuran to the corresponding lactones either by direct C-glycosidation of the O-acetyl derivatives with furan; the resultant 2-furyl C-glycosides are converted to carboxylic acids by the oxidative cleavage of the furan nucleous.
