An attempt was made to use a simple procedure to obtain (R)- and (S)-2-aminobutanoic acids [(R)- and (S)-1] which are non-proteinogenic alpha-amino acids and are useful as chiral reagents in asymmetric syntheses. Compound (RS)-1 p-toluenesulfonate [(RS)-2], which is known to exist as a conglomerate, was optically resolved by replacing crystallization with (R)- and (S)-methionine p-toluenesulfon...

Enantioselective production of (S)-2-phenyl-1-propanol is important as in order to be applied industry, a high degree optical purity required. Besides organocatalysts and metal complexes, biocatalysts can used for its synthesis their isolated form or whole-cell biocatalysts, both which have various advantages disadvantages. In this research, Saccharomyces cerevisiae, biocatalyst, recombinant ho...

Combinations of TiO2 photocatalysts and various adsorbents have been widely studied for the adsorption and photocatalytic decomposition of gaseous pollutants such as volatile organic compounds (VOCs). Herein, a TiO2-zeolite-porous glass composite was prepared using melt-quenching and partial sintering, hydrothermal treatment, and drop coating for preparation of the porous glass support and X-ze...
