A practical procedure for carbonyl α-oxidation: synthesis of (2-benzoyloxy)-1,4-cyclohexanedione mono-ethylene ketal was written by Jones, Teyrnon C.;Tomkinson, Nicholas C. O.. And the article was included in Organic Syntheses in 2007.SDS of cas: 33439-27-9 This article mentions the following:
A convenient method for the preparation of α-acyloxy ketones is described. Oxyacylation of a variety of ketones with O-acyl hydroxyamine derivatives provided the corresponding α-acyloxy ketones in good yields. (2-Benzoyloxy)-1,4-cyclohexanedione mono-ethylene ketal was successfully synthesized from 1,4-cyclohexanedione mono-ethylene ketal. In the experiment, the researchers used many compounds, for example, 1-Tosylpiperidin-4-one (cas: 33439-27-9SDS of cas: 33439-27-9).
1-Tosylpiperidin-4-one (cas: 33439-27-9) belongs to piperidine derivatives. The piperidine moiety constitutes an important building block for the synthesis of a variety of bioactive natural products, alkaloids and other drugs. Some chemotherapeutic agents have piperidine moiety within their structure, foremost among them, vinblastine and raloxifene.SDS of cas: 33439-27-9
