| Abstract: | Novel dialkylphosphonates of arteannuin B were synthesized in 45-47% yields by reaction of this cadinanolide with dialkylphosphites. Their structures were established using IR, PMR, 13C and 31P NMR spectroscopy, and two-dimensional 1H-1H NMR (COSY) spectroscopy. The reaction of arteannuin B and dialkylphosphites is highly stereoselective. |
