The absolute configuration of vibsanin F (1), one of the simplest 11-membered ring vibsane-type diterpene, was established to be 6R, 7S and 11S by asymmetric synthesis. A diastereomer (1a) with a 6S, 7S and 11S configuration was synthesized starting from myrcene by procedures featuring a Sharpless a
D-Glucose, D-mannose and L-rhamnose were reacted with a racemic mixture of 2-butanol, and the resulting alpha-glycosides were analyzed by 1H NMR with COSY and NOESY experiments. Conformational analysis of alpha-glycosidic bonds performed with molecular modeling and appropriate heteronuclear long-ran
