Vetica, Fabrizio published the artcileDesymmetrization of Cyclopentenediones via Organocatalytic Cross-Dehydrogenative Coupling, Application of 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, the publication is Advanced Synthesis & Catalysis (2017), 359(21), 3729-3734, database is CAplus.
An enantioselective synthesis of cyclopentenediones bearing a pyrazole unit was achieved through an organocatalytic Michael addition/oxidation process. This desymmetrization reaction led to the desired pyrazole-cyclopentenediones with high yield and good enantioselectivities. The postulated cross-dehydrogenative coupling-mechanism was investigated via preliminary control experiments
Advanced Synthesis & Catalysis published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C6H3ClFNO2, Application of 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone.
