Enantioselective Synthesis of the C(1)-C(6?) Subunit of Zaragozic Acid C

Journal of the Brazilian Chemical Society, 1998
Preparation of the C(1)-C(6?) subunit of Zaragozic acid C is described. The C(5?) methyl-bearing stereocenter is installed by rapid, regioselective opening of a phenylcyclopropyl carbinol with Pearlman?s catalyst (1 atm H2) in 2% triflic acid/methanol.

Applications of Nanozymes in Chiral-Molecule Recognition through Electrochemical and Ultraviolet–Visible Analysis

Molecules
Chiral molecules have similar physicochemical properties, which are different in terms of physiological activities and toxicities, rendering their differentiation and recognition highly significant. Nanozymes, which are nanomaterials with inherent enzyme-
