Abstract :
Two new angucycline compounds containing O-glycosylated 6-deoxy-α-l-talose were isolated from Kitasatospora sp. The compounds were elucidated based on spectroscopic methods including UV, HR-ESIMS, and NMR. A feeding experiment using alizarin led to the conversion of alizarin to a monoglycosylated product with high efficiency, which allows isolation of the sugar after hydrolysis and determination of the absolute configuration of the sugar.
