Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Product Details of 638-07-3

Convenient one-step synthesis of quinoline-3,4-dicarboxylate derivatives was written by Ge, Youjin;Yu, Niefang. And the article was included in Synthetic Communications in 2021.Product Details of 638-07-3 The following contents are mentioned in the article:

Herein a practical and convenient procedure for the one-step synthesis of quinoline-3,4-dicarboxylate derivatives from isatins and β-keto esters in alcs. catalyzed by sulfuric acid was described. This novel protocol offers the advantages of high conversion rates, short reaction times, and easy handling. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Product Details of 638-07-3).
