✦ Synopsis

The axial C6-OH group in gambierol isolated from the dinoflagellate, Gambierdiscus toxicus, was inverted to equatorial disposition and esterified with (S)-and (R)-MTPA. NMR analysis of these esters established S configuration at C6, thus allowing determination of the absolute configuration of the whole rnoleeule.
