A highly regio-and stereoselective dihydrocyanation of 1,3-enynes was implemented by nickel/diphosphine catalysts. This reaction represents the first example of Ni-catalyzed dihydrocyanation of 1,3-enynes using TMSCN and MeOH as HCN surrogates. In this tr
Palladium-catalyzed cyclization of vinyl iodide-tethered allensulfonamide

This Letter describes a palladium-catalyzed cyclization of vinyl iodide-tethered allensulfonamide in the presence of alkylol, which provides a facile access to 2-alkoxy-3-methylene-tetrahydropyridine. The asymmetric version of this reaction has also been preliminarily realized with up to 81% enantioselectivity when chiral bisphosphine ligands were used.
Synthesis of pinacol arylboronates from aromatic amines: A metal-free transformation

A metal-free borylation process based on Sandmeyer-type transformation using arylamines derivatives as the substrates has been developed. Through optimization of the reaction conditions, this novel conversion can be successfully applied to a wide range of aromatic amines, affording borylation products in moderate to good yields. Various functionalized arylboronates, which are difficult to access by other methods, can be easily obtained with this metal-free transformation. Moreover, this transformation can be followed by Suzuki-Miyaura cross-coupling without purification of the borylation products, which enhances the practical usefulness of this method. A possible reaction mechanism involving radical species has been proposed.
