(R)-Mosher diester 11.'' The diols 13 and 14 were also ... R L OH MeOyC02 Ph CF3 10 11 ... 12 prepared from the reaction of the aldehydes with reagent 12.12 Again, the diastereoselectivity of the reaction was determined from the 'H NMR spectra and the enantios- electivity from an examination of the derived Mosher diester 15. All these results are also included in Table I. It is interesting to note that although the reaction of the aldehyde 6 with reagent 5 gave only a single diol ...
