Wittig reactions have been developed for the synthesis of chiral 2,5-dihydro-1 H -pyrrole and tetrahydropyridine derivatives. These processes have been rendered catalytic in phosphine, thanks to the in situ reduction of phosphine oxide by phenylsilane. Furthermore, catalytic and asymmetric P(III)/P(V) processes were implemented using enantiopure chiral phosphines.

visible light-mediated atom transfer radical addition (ATRA) of haloalkanes onto alkenes and alkynes using the reductive and oxidativequenching of [IrdF(CF(3))ppy}(2)(dtbbpy)]PF(6) and [Ru(bpy)(3)]Cl(2) is presented. Initial investigations indicated that the oxidativequenching of photocatalysts could effectively be utilized for ATRA, and since that report, the protocol has been expanded by broadening

Stuck with the right choice: αvβ3‐ or α5β1‐selectiveintegrin ligands were functionalized for surface coating without losing activity and selectivity. The coating of nanostructured gold surfaces with these compounds stimulated subtype‐selective cell adhesion of genetically modified αvβ3‐ or α5β1‐expressing fibroblasts in vitro.
