Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Organic & Biomolecular Chemistry called Asymmetric α-alkylation of cyclic β-keto esters and β-keto amides by phase-transfer catalysis, Author is Wang, Yakun; Li, Yueyun; Lian, Mingming; Zhang, Jixia; Liu, Zhaomin; Tang, Xiaofei; Yin, Hang; Meng, Qingwei, which mentions a compound: 3395-91-3, SMILESS is O=C(OC)CCBr, Molecular C4H7BrO2, SDS of cas: 3395-91-3.
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
