SECONDARY MOLD METABOLITES .45. ISOLATION AND STRUCTURE ELUCIDATION OF SULCATINE-G, A NOVEL SESQUITERPENE FROM LAURILIA-SULCATA

The structure and the relative configuration of sulcatine G 1a, a new sesquiterpene isolated from still cultures of Laurilia sulcata, has been assigned on the basis of H-1 and C-13 NMR spectroscopy studies; sulcatine G possesses a new ring skeleton which may be derived by contraction of the six-membered ring of a protoilludene sesquiterpenoid.
