The clemmensen reduction of α,β-unsaturated ketones The deoxygenation of the [alpha],[beta]-unsaturated ketones (1) and (5) under the Clemmensen condition yielded the olefins (2) and (6) along with their respective dimers (3+4) and (8+9). The [alpha] , [beta]-unsaturated ketone (...
Alpha-beta unsaturated ketone derivatives useful as herbicides Herbicidal compounds of the formula (I): wherein A is oxygen or sulphur; X is a 1-(1,2,4- triazolyl) or 1-imidazolyl radical; R' is an aliphatic or cycloaliphatic radical substituted by one or more of the following: halogen,...
PURPOSE: To obtain a new α,β-unsaturated ketoester derivative useful as an intermediate for producing, under mild conditions in a short process, a 2,4- dihydroxypyridine derivative as an inhibitor of an in vivo decomposing enzyme of 5-fluorouracyl which is an anti-malignant tumor...
The hydrogen transfer mechanism of cofactor reduction and recycling processes in the yeast reduction of α,β-unsaturated ketone was studied by using quantitative isotope tracing close to natural abundance measured by 2H NMR. In the reaction, the active cofactor is NADPH. The cofactor-transferred hydr...
