Allylic axial chirality rule

The intrinsic contribution, accounted for by the diene rule, seems to be easily outweighed by the perturbations arising from the allylic axial substituents, which in turn define the allylic axial chirality rule. This latter can be formulated in two ways The olefin-picture , where chirality is referred to the nearest double bond, and the diene-picture ,... [Pg.131]

Fresh evidence is presented that the lowest-energy singlet electronic c.d. band in several chiral mono-olefins is associated with the -> 35 Rydberg transition. Inadequacies of the diene chirality rule have become apparent from recent data. C.d. effects of cyclohexa-1,3-dienes seem to be due as much to allylic axial substituents as to the diene chirality. The effect is well illustrated by the series of... [Pg.231]
