Application of two-dimensional nmr spectroscopy in the structural determination of marine natural products. Isolation and total structural assignment of 4-deoxyasbestinin diterpenes from the Caribbean gorgonian Briareum asbestinum.

J J Morales1, D Lorenzo, A D Rodríguez.   

Abstract

The structures of four novel asbestinin diterpenes isolated in the toxic extracts of the Caribbean gorgonian Briareum asbestinum are discussed. The major metabolite 11-acetoxy-4-deoxyasbestinin B was subjected to a total structural assignment through the concerted application of several 2D nmr techniques that included 1H-1H COSY, RCT-COSY, RCT2 COSY, HC COSY (HMQC), NOESY, proton-detected long range heteronuclear chemical shift correlation (HMBC) and 13C-13C chemical shift correlation spectroscopy (INADEQUATE).
