A variety of 2,3-diiodinated biphenyl and iodinated meta-terphenyl derivatives were synthesized by a regioselective Suzuki-Miyaura cross-coupling reaction of 5-substituted 1,2,3-triiodobenzenes. By using 1 equiv. of arylboronic acid, the Suzuki-Miyaura re

An effective shielding of both apical positions of a neutral NiII active site is achieved by dibenzosuberyl groups, both attached via the same donors’ N-aryl group in a Cs-type arrangement. The key aniline building block is accessibl

The Kinetic Resolution (KR) of α-alkylated enolisable disubstituted anhydrides has been shown to be possible for the first time. In the presence of an ad hoc designed novel class of bifunctional sulfamide organocatalyst, a regio-, diastereo- and enantioselective cycloaddition reaction between the enolisable anhydride and benzaldehydes provides densely functionalised γ-butyrolactones in one pot (up to 19:1 dr, 94% ee) with control over three contiguous stereocentres. The concomitant resolution of the starting material anhydride, provides access to a range of chiral succinate derivatives with selectivity factors up to S? = 10.5.
