Abstract:
A novel secondary metabolite, N-trans-cinnamoyl 2-amino-3a,4,5,6,7,8,9,10,11,12,13,13a-dodecahydrocyclododeca[d]oxazole (1), was isolated from Streptomyces spp. CIBYL1, along with five known compounds, pimprinine (2), (3R,4S,5R,6R)-3,4,5,6-tetrahydro-4-hydroxy-3,5,6-trimethyl-2H-pyran-2-one (3), indolyl-3-carboxylic acid (4), 2-phenylacetamide (5) and di(1H-pyrrol-2-yl)methanone (6). The structures of these metabolites were elucidated on the basis of extensive analysis of spectroscopic data, including OR, IR, HRMS, 1D and 2D NMR data and chemical derivation.
