Asymmetric Construction of α-Substituted β-Hydroxy Lactones via Ni Catalyzed Decarboxylative Addition Reaction

We described a Ni-bidentate oxazoline catalyzed highly enantio- and diastereoselective decarboxylative aldol reaction of 2-oxotetrahydrofuran-3-carboxylic acid/2-oxochromane-3-carboxylic acid derivatives with different kinds of carbonyls. Under optimal reaction conditions, α-substituted β-hydroxy butyrolactones and dihydrocoumarins with an all-carbon quaternary stereocenter have been generated with high levels of functional-group compatibility. Furthermore, proficient transformations of products were also described, in which an aliphatic tertiary alcohol and a multi-substituted 1,4-diol were smoothly constructed through hydrogenation and ring-opening reaction, respectively.

Iodine mediated a simple strategy for the synthesis of β,γ-unsaturated-α-ketoesters and its application for the synthesis of 4,5-dihydropyrazole derivatives

Abstract: Novel and efficient method for the synthesis of a series of β,γ-unsaturated-α-ketoesters under mild conditions was developed. This one-step protocol was achieved by the reaction of electron-rich aromatic aldehydes and pyruvates in the presence o

Direct Synthesis of β,γ-Unsaturated α-Keto Esters from Aldehydes and Pyruvates

Herein, we describe two practical methods to synthesize β,γ-unsaturated α-keto esters directly from aldehydes and pyruvates promoted by BF 3 ?Et 2 O in the presence of Ac 2 O or by Ti(OEt) 4 under mild condition
