The emission properties of three 4-azafluorenone and five new α-carboline fluorophores in both solution and thin solid films were investigated. Fluorescence of the azafluorenone is clearly enhanced in thin solid films due to the presence of phenyl/b

The organocatalytic addition of substituted oxyacetaldehydes to 2-acylaminonitroethenes proceeded with good to high diastereoselectivities and enantioselectivities. The resulting adducts reacted with ethyl 2-(diethoxyphosphoryl) acrylate to afford hi

The use of monophos as a ligand in the palladium-catalyzed Suzuki diarylation of 2,2′-diiodo-1,1′-binaphthyl under optimized conditions followed a stereoconservative course. However, some chiral P ligands were found to be capable of inducing ster

Suzuki diarylation of enantiopure 2,2′-diiodo-1,1′-binaphthyl catalyzed by triphenylphosphane palladium complex is accompanied by almost complete racemization of binaphthyl moiety (7% e.e.). Based on formerly proposed mechanism, secondary oxidati

An effective methodology has been developed for the synthesis of enantiopure 2,2'-dialkynylated 1,1'-binaphthalene derivatives. Enantiopure 2,2'-diiodo-1,1'-binaphthalene (10) provided 2,2'-diethynyl-1,1'-binaphthalene (16) in the Negishi alkynylatio

The Suzuki arylation of enantiopure 2,2'-diiodo-1,1'-binaphthalene affords the 2,2'-diarylated products in considerable yields (up to 52%), however, significantly racemized. The reversed-polarity approach, using novel enantiopure 1,1'-binaphthalene-2

The first preparation of enantiomerically pure 1,1′-binaphthyl-2,2′-diboronic acid (by resolution) is reported. Optimization of the cross-coupling conditions was found to be crucial to achieve good yields in Suzuki arylation in approaches from bo
