Abstract: Cu/(Ph-pybox)-catalyzed asymmetric dearomative alkynylation of isoquinolines has been realized in high to excellent enantioselectivities (up to 96% ee) with α-bromoacetophenone as an activator and 1,1′-binaphthyl-2,2′-diyl hydrogenphosphate as an additive. This novel reaction tolerates a wide… read more here.

Abstract: Catalytic asymmetric dearomatization (CADA) reactions is an important synthetic method for constructing enantioenriched complex cyclic systems from simple aromatic feedstocks. However, the CADA reactions of nonactivated arenes, such as naphthalenes and benzenes, have been far… read more here.

Abstract: Abstract Chiral N-heterocyclic organoboronates represent promising intermediates for the preparation of various bioactive and pharmaceutical compounds. We recently reported the first asymmetric dearomative borylation of indoles by copper-catalyzed borylation. Then we further developed dearomatization/enantioselective borylation… read more here.
