ChemInform Abstract The pseudo-first-order rate constants, obtained for the title reactions with butylamine, glycine, glycylglycine, and ethylenediamine monohydrochloride, lead to Bronsted coefficients 0.66 and 0.49 for the 2-isomer and the 4-isomer, respectively.

The enzymatic reduction of 1‐phenyl‐1,2‐propanedione (I) with fermenting bakers' yeast is compared to other literature methods.
