Mahajan, Suruchi published the artcileEnantioselective synthesis of pyrazolone α-aminonitrile derivatives via an organocatalytic Strecker reaction, COA of Formula: C10H9ClN2O, the publication is Chemical Communications (Cambridge, United Kingdom) (2017), 53(49), 6633-6636, database is CAplus and MEDLINE.
A new organocatalytic enantioselective Strecker reaction of pyrazolone-derived ketimine electrophiles was developed. Using pseudo-enantiomeric squaramide catalysts the nucleophilic 1,2-addition of trimethylsilyl cyanide to the ketimines efficiently provided a direct entry to both enantiomers of pyrazolone α-aminonitrile derivatives at will in good yields and high enantioselectivities for a wide variety of substrates.
Chemical Communications (Cambridge, United Kingdom) 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 C10H9ClN2O, COA of Formula: C10H9ClN2O.
