High-field FT NMR application of Mosher's method. The absolute configurations of marine terpenoids

Mosher's (H-1) method to elucidate the absolute configuration of secondary alcohols was reexamined by use of high-field FT NMR spectroscopy, which enables assignment of most of the protons of complex molecules. There is a systematic arra...

Synthesis and absolute stereochemistry of serricornin [(4S,6S,7S)-4,6-dimethyl-7-hydroxy-3-nonanone]. The sex pheromone of the cigarette beetle

The absolute stereochemistry o serricornin (4,6-dimethyl-7-hydroxy-3-nonanone) was established as 4 S, 6 S, 7 S by synthesizing both (4 S, 6 S, 7 S)-isomer and its antipode. Only the natural enantiomer was bioactive.
