33 wherein non-equivalence of several signals was observed. On the other hand, when (-)-17 and (-)-18 were employed under otherwise identical conditions, only single absorptions were observed for the same signals. These experiments unequivocally demonstrate that both the cycloaddition precursors and adducts are single enantiomers, and by extrapolation so are subsequent intermediates.
