摘要：

A novel scalarane derivative (2) has been isolated from the marine sponge Carteriospongia foliascens. A complete assignment of the H-1 and C-13 n.m.r. spectra of (2) was achieved by using COSY-90, H-1-detected H-1/C-13 correlation (HMQC sequence) and H-1-detected long-range H-1/C-13 correlation (HMBC sequence) experiments, all measured at 600 MHz. The assignment of stereochemistry at C4 was supported by a ROESY spectrum.
