Abstract:
Polarity inversion is the hallmark of N-heterocyclic carbene (NHC) organocatalysis, with the generation and reaction of acyl anion equivalents known for more than 70 years. In contrast, polarity inversion through 1,4-addition of NHCs to conjugate acceptors was first applied in a catalytic reaction in 2006. This sub-field of NHC-organocatalysis has developed steadily over the subsequent years, enabling novel coupling reactions, enantioselective cycloisomerizations, polymerizations, and other reactions. In this review, this emerging area of NHC-organocatalysis is discussed with comprehensive cov

Abstract:
Asymmetric synthesis of helicenes and their congeners has been demonstrated to rely either on enantioselective Ni0/PR3*-catalyzed [2+2+2] cycloisomerization of triynes or on diastereoselective CoI-catalyzed [2+2+2] cycloisomerization of chiral triynes. The former approach providing tetrahydrohelicenes in a nonracemic form requires further development as moderate enantioselectivities (up to 54 % ee) have so far been achieved under kinetic control. The latter approach affording helicene-like structures in a diastereomerically enriched form allows for reaching good to excellent diastereoselectivi

Abstract:
The preparation of novel MeOBIPHEP atropisomeric chiral congener ligands via an efficient palladium-catalyzed P–C coupling key step is described. We demonstrate that these palladium-catalyzed conditions are compatible with the brominated MeOBIPHEP backbone. The reaction conditions for asymmetric silver-catalyzed cycloisomerization of γ-allenols were optimized, leading to the first enantioselective catalytic system employing atropisomeric diphosphine ligands as the chiral inducer. The process follows a major 5-exo cyclization via addition of the alcohol moiety to the π-activated allenyl interme
