✦ Synopsis

In the course of our chemical screening program, the novel acyl α-L-rhamnopyranosides (1-6) were detected as metabolites from five different strains of Streptomycetes. The structures of all these compounds were elucidated by chemical and spectroscopic methods. The biosynthesis of 1 and 3 was established by feeding 13 C-labelled acetate, glycerol, and dglucose to Streptomyces griseoviridis (strain Tü 3634), and resulted in a complete labelling pattern of the 2,4-dimethyl-
