Notes:
The stereochemical assignments of coleonol-B (1), coleonol-D (2) and coleosol (3) were accomplished by 2D 1H—1H (COSY), 1H—13C (hetero COSY), NOE difference NMR spectroscopic, stereospecific coupling constant and selective heteronuclear spin decoupling studies. The complete 13C chemical shift assignments of 2, 3 and coleol (4) were made for the first time. The earlier 1H chemical shift assignments were corrected and the stereostructure of coleonol-D was reassigned.
