Inversion of Diastereoselectivity Depending on Substrate Concentration in Baker’s Yeast Catalyzed Reduction of σ-Symmetrical 1,3-Cyclopentadiones and 1,3-Cyclohexadiones
Inversion of Diastereoselectivity Depending on Substrate Concentration in Baker’s Yeast Catalyzed Reduction of σ-Symmetrical 1,3-Cyclopentadiones and 1,3-Cyclohexadiones
Synthesis of Racemic and Enantiomerically Pure Acetylenic ω-Keto Esters Derived from 2-Methyl-1,3-cycloalkanediones and 2-Methylcycloalkanones Respectively
Racemic and enantiomericallypure alkynyl esters tethered, respectively, to 2-methyl-1,3-cycloalkanediones and 2-methylcycloalkanones were readily obtained starting from common intermediates, which were available on large scale. alkynyl ester - enantiomer-chain - elongation - trimethylsilylpropyne - Corey-Fuchs reaction
