Hsung, Richard P.’s team published research in Journal of Organic Chemistry in 1999 | CAS: 50743-32-3

6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile(cas: 50743-32-3) belongs to nitriles. Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons.Synthetic Route of C13H11NO2

Synthetic Route of C13H11NO2On November 12, 1999 ,《A Rare Acid-Promoted Elimination of O-Methyl Oximes: A Practical Synthesis of 3-Cyano-4-benzopyrones》 appeared in Journal of Organic Chemistry. The author of the article were Hsung, Richard P.; Zificsak, Craig A.; Wei, Lin-Li; Zehnder, Luke R.; Park, Francis; Kim, Michelle; Tran, Thuy-Trang T.. The article conveys some information:

3-Cyano-4-benzopyrones I (X = H, 6-Me2CH, 6-Cl, etc.) were prepared by acid-promoted elimination of O-Me oximes II (mixture of syn and anti). The experimental part of the paper was very detailed, including the reaction process of 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile(cas: 50743-32-3Synthetic Route of C13H11NO2)
