Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 3395-91-3, is researched, Molecular C4H7BrO2, about Asymmetric α-alkylation of cyclic β-keto esters and β-keto amides by phase-transfer catalysis, the main research direction is indanone preparation enantioselective; keto ester alkyl bromide alkylation cinchona phase transfer catalyst; amide keto alkyl bromide alkylation cinchona phase transfer catalyst; tetralone preparation enantioselective.Synthetic Route of C4H7BrO2.
Without employing any transition metal, a highly enantioselective α-alkylation of cyclic β-keto esters and β-keto amides has been realized by phase-transfer catalysis. This improved procedure is applicable to different kinds of bromides with cinchona derivatives and gives the corresponding products e.g., I and e.g., II, in excellent enantiopurities (up to 98% ee) and good yields (up to 98%). Moreover, the reaction was scalable and the phase-transfer catalyst was recyclable. This provided an alternative and competitive method to the asym. α-alkylation of β-dicarbonyl compounds
