This study focuses on the Baeyer-Villiger reaction of propanone and performic acid, with formic acid as catalyst. Continuum solvation methods (EIF-PCM and CPCM) and two density functionals (B3LYP and MPWB1K) are used to study solvent effects on two types of reaction mechanisms: concerted non-ionic and stepwise ionic. The ionic mechanism is the one found in most organic chemistry textbooks; it b...

Phenylacetone monooxygenase (PAMO) from Thermobifida fusca is a FAD-containing Baeyer-Villiger monooxygenase (BVMO). To elucidate the mechanism of conversion of phenylacetone by PAMO, we have performed a detailed steady-state and pre-steady-state kinetic analysis. In the catalytic cycle ( k cat = 3.1 s (-1)), rapid binding of NADPH ( K d = 0.7 microM) is followed by a transfer of the 4( R)-hydr...

10-((4-Hydroxypiperidin-1-yl)methyl)chromeno[4,3,2-de]phthalazin-3(2H)-one (E7016), an inhibitor of poly(ADP-ribose) polymerase, is being developed for anticancer therapy. One of the major metabolites identified in preclinical animal studies was the product of an apparent oxidation and ring opening of the 4-hydroxypiperidine. In vitro, this oxidized metabolite could not be generated by incubati...

a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...
