48 using 70 % phosphoric acid as the reaction medium. Repetition of one of the preparations (2,r-4,cis-5-tri-i-Pr-1,3-dioxolane) in this study essentially confirmed the report (92 % of the syn and 8 % of the anti isomer was obtained). The reasoss for the high stereoselectivity in these largely kinetically controlled reactions are not clear report preparation ratios of 4:1 (syn:anti) and 3:1 (cis:trans) for diastereoisomeric mixtures of 2-methyl-4-cis-5-chloromethyl- and 2-methyl-4-(methyl-cis-chloromethyl)-1,3-dioxolane, respectively

The calculation of specific torsional angles from coupling constants in five-membered rings is probably a dangerous procedure. It has been pointed out by that coupling constants should properly be integrated over the whole rotation circuit of conformationally mobile molecules rather than just summed over the most stable conformations. In five-membered rings where the energy wells are not so deep and pseudorotation or pseudo-libration may lead to rather wide conformational circuits, Tabacik's objection should be particularly pertinent and the classical procedure of assuming that the averaging of one, two, or three conformations with their appropriate torsional angles can be made to explain the observed coupling constants may be quite bad
