A new linear polyketide, juniperolide A (1), was produced by the terrestrial actinomycete (Lv1-48) isolated from the rhizosphere of the plant Juniperus excelsa. The juniperolide A (1) structure contains a THP unit and a 3-amino-2,3,6-trideoxyhexose as the glycosidic moiety. Mosher’s analysis was used for absolute stereochemistry determinations at C-2, C-8, C-20, and C-4′, while the relative stereochemistry assignments of the remaining stereocenters were based on ROESY correlations and J-based coupling.
