with either MeONa/MeOH or HCl/MeOH solutions. Triethylamine catalyzed cyclisation of 6 led to a 15:85 mixture of 1A and 1B. The cis relationship of the OH and P=O groups in 1A and 7A was established by 1H and 13CNMR spectra. Predominant conformations of 1A and 1B and their derivatives were deduced from 3JHCCP and 3JCCOP coupling constants. A possible mechanism of the transformations described in the paper
