Notes:
High-field 1H NMR studies of himachalol (1) have been carried out by two-dimensional NMR methods. The stereochemical aspects of this molecule were studied through the application of stereospecific coupling constants, the nuclear Overhauser effect and lanthanide-induced chemical shifts. Complete and unambiguous 13C chemical shift assignments of 1 have been made for the first time by using two-dimensional heteronuclear (1H—13C) correlation NMR spectroscopy, DEPT, broad-band proton decoupling and selective heteronuclear spin decoupling 13C NMR methods. Complete 13C chemical shift assignments of isocentdarol, centdarol and centdarone have also been made using some of the above techniques and their stereostructures have been corrected.
