A one-pot transformation of biaryl dicarboxylic acids to (NH)-phenanthridinone derivatives based on a Curtius rearrangement and subsequent basic hydrolysis was developed. This method is also applicable for the preparation of optically active amide-fu

Novel well-defined D2-symmetric dirhodium(II) carboxylate complexes that bear axially chiral binaphthothiophene delta-amino acid derivatives have been developed. Conformational control was achieved through chalcogen-bonding interactions between sulfu

Axially chiral binaphthothiophene dicarboxylic acid was prepared as a novel functionalized chiral dicarboxylic acid. The crystal structures of both the racemic form and its salt with chiral diamine revealed the intramolecular S···O interactions (c

Axially chiral amino acid derivatives were synthesized via a selective single-step monoesterification of 1,1′-binaphthyl-2,2′-dicarboxylic acids. In the presence of Ag2CO3, the alkylative monoesterification of a 1,1′-binaphthyl-2,2′-dicarboxy

The scope and limitations of the platinum catalyzed 7-endo cyclization of internal alkynyl amides were investigated. Substitution of the alkyne with an aryl group gave better results, presumably because it stabilized the transition state. Applying th
