On October 28, 2019, Fan, Lian-Feng; Wang, Tian-Ci; Wang, Pu-Sheng; Gong, Liu-Zhu published an article.SDS of cas: 10472-24-9 The title of the article was Palladium-Catalyzed Asymmetric Allylic C-H Alkylation of 1,4-Dienes with Cyclic β-Keto Esters. And the article contained the following:
In the presence of chiral phosphoramidite ligand, a palladium-catalyzed asym. allylic C-H alkylation of 1,4-dienes with cyclic β-keto esters has been established to afford chiral α,α-disubstituted β-keto esters I (3, R1 = H, Me, F, OMe, Cl, OCH2CH:CH2, OCH2CCMe; R2 = Me, Et, iPr, tBu, PhCH2; R = alkyl, cycloalkyl, Ph, carboxy, carboxamide) in good to excellent yields, with high levels of regioselectivity, E/Z selectivity, and enantioselectivity. 1,4-Dienes bearing a wide scope of functional groups, such as ketone, chloride, ester, and amide as well, have been nicely tolerated. In addition, preliminary application of this method enables a concise formal synthesis of (-)-tanikolide. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).SDS of cas: 10472-24-9
