Carbon− heteroatom bond formations are very important reactions in organic synthesis and
have attracted the interest of many synthetic organic chemists, leading them to develop new …

Conspectus To improve the field of catalysis, there is a substantial and growing need for
novel high-performance catalysts providing new reactivity. To date, however, the set of …

Stereoselective protonation is a challenge in asymmetric catalysis. The small size and high
rate of transfer of protons mean that face-selective delivery to planar intermediates is hard to …

Abstract An asymmetric 1, 6‐conjugate addition of thioacetic acid with para‐quinone
methides has been developed by using chiral phosphoric acid catalysis in the presence of …

Atropisomerism is a fundamental property of molecules featuring a hindered rotation around
a chemical bond. If six-membered ring biaryl or heterobiaryl atropisomers are the most …

Pinches like a crab: The utilization of guanidines as catalysts has been growing at a steady
pace. They possess high pKa values and activate through dual hydrogen‐bonding modes of …

PROTONtype: An NHC‐catalyzed (NHC= N‐heterocyclic carbene), highly asymmetric
intermolecular Stetter reaction allows the atom‐economic and efficient formation of valuable …

Conspectus Catalysts accelerate biological processes and organic reactions in a controlled
and selective fashion. There are continuing efforts in asymmetric catalysis to develop …

We report that chiral bicyclic guanidine 1 is found to catalyze the isomerization of alkynes to
chiral allenes with high enantioselectivities. This Brønsted base catalyzed 1, 3-proton shift …

Herein we describe the enantioselective intermolecular conjugate addition of nitroalkanes to
unactivated α, β‐unsaturated esters, catalyzed by a bifunctional iminophosphorane (BIMP) …
