Synthesis of Belallosides of Belamcanda Chinesis and its Analogs

Two compounds namely Belallosides A and B (6-O-benzoyl esters of 2-methoxy-4-acetyl-O-phenyl-β-glucopyranosides) isolated from Thai medicinal plant Belamcanda chinesis were synthesized by using simple approach. Further, three new analogs (1c-1e) of the belallosides (1a and 1b) were also synthesized by using the approach. The yields of the compounds were also good.
