Cyano phosphate: an efficient intermediate for the chemoselective conversion of carbonyl compounds to nitriles was written by Yoneda, Ryuji;Harusawa, Shinya;Kurihara, Takushi. And the article was included in Journal of Organic Chemistry in 1991.SDS of cas: 33439-27-9 This article mentions the following:
Cyanohydrin di-Et phosphates, readily obtained from various ketones and aldehydes by reaction with di-Et phosphorocyanidate and lithium cyanide, reacted chemoselectively with SmI2 in THF to give the corresponding nitriles in excellent yields. This method was also found applicable to α,β-unsaturated carbonyl compounds via cyano phosphates to give β,γ-unsaturated nitriles, not obtainable by standard methods, without isomerization of the double bonds. 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. Piperidine and its derivatives have become increasingly popular in many synthetic schemes. Some chemotherapeutic agents have piperidine moiety within their structure, foremost among them, vinblastine and raloxifene.SDS of cas: 33439-27-9
