Figure 1. (IMAGE) Institute for Basic Science Caption (a) Outline of the novel iridium based catalyst's access to carbocation intermediates, which achieves both high regioselectivity (>95%) and enantioselectivity (>98%). (b) Computational modeling for proving the intermediacy of carbocation and for understanding the selectivity-determining step.
