TL;DR: A unique binary chiral phosphoric acid 1a/MgF(2) catalyst that enables effective catalysis of asymmetric Friedel-Crafts reactions of phenols with up to 82% yield and >99% ee is presented.
TL;DR: A new asymmetric binary acid catalyst was developed to promote 1,5-H transfer specifically and stereoselectively in tert-aminocyclization reactions with excellent activity, high enantioselectivity, and broad substrate scope.
Abstract: Selective H transfer by ABC: A new asymmetric binary acid catalyst was developed to promote 1,5-H transfer specifically and stereoselectively in tert-aminocyclization reactions with excellent activity, high enantioselectivity, and broad substrate scope. The H atom (in red) was proven to transfer through a stereospecific suprafacial pathway (see scheme).
TL;DR: The authors showed that swapping the anions of an indium Lewis acid leads to a remarkable regioselectivity switch between asymmetric 1,2-and 1,4-addition reactions of N-protected indoles (II) and β,γ-unsaturated α-keto esters (III).

TL;DR: The exchange of the metal ion from In(III to Sc(III) in a binary acid catalyst leads to a switch in the diastereoselectivity of [4 + 2] cycloadditions as discussed by the authors.
