Synthesis and crystal structures of chiral ferrocene and ruthenocene substituted aminomethylnaphthols obtained through Betti-condensation
Autor: Svetlana Simova, Kalina Kostova, Krasimira Dikova, Angel Chimov, Anthony Linden, Vladimir Dimitrov
Ferrocene- and ruthenocenecarboxaldehydes have been employed in Betti-type condensation reactions with 2-naphthol and (S)-phenylethylamine to give metallocenyl-substituted aminomethylnaphthols in a diastereoisomerically pure form. The absolute config

Publikováno v: Polyhedron. 45:126-143
Series of functionalized organolithium compounds were prepared and added to chiral bicyclic ketones (1R-(+)-camphor analogue 2 and 1R-(−)-fenchone 3), resulting in the preparation of a small “library” of chiral aminoalcohols able to serve as li

Synthesis of ferrocene-based amido-phosphine ligands via highly diastereoselective ortho-lithiation and their application in Pd-catalyzed asymmetric allylic alkylations
Autor: Boris Shivachev, Georgi Stavrakov, Angel Chimov, Irena Philipova, Vladimir Dimitrov, Rositsa P. Nikolova
Publikováno v: Tetrahedron: Asymmetry. 22:970-979
An efficient synthesis of novel planar chiral ferrocene-based amido-phosphine ligands was accomplished via highly diastereoselective ortho-lithiation and subsequent in situ trapping with chlorodiphenylphosphine. The palladium complexes of mono-phosph

Synthesis and in vitro antimycobacterial activity of compounds derived from (R)- and (S)-2-amino-1-butanol - The crucial role of the configuration
Autor: Pavleta Tzvetkova, Georgi M. Dobrikov, Margarita Stoilova-Disheva, Georgi Momekov, Angel Chimov, Violeta Valcheva, Vladimir Dimitrov
Publikováno v: European journal of medicinal chemistry. 48
The synthesis of 47 structurally diverse compounds incorporating the (R)-2-amino-1-butanol motif has been realized. Ten of these compounds were found to exhibit in vitro specific activity against Mycobacterium tuberculosis H37Rv in a MIC range of 0.6
