Elemental Sulfur/DMSO-Promoted Multicomponent One-pot Synthesis of Malonic Acid Derivatives from Maleic Anhydride and Amines
Nguyen, Le Anh,Retailleau, Pascal,Nguyen, Thanh Binh
, p. 2864 - 2869 (2019/05/01)
Malonic acid derivatives could be conveniently prepared with high degree of functional flexibility via redox condensation reactions between anhydride maleic, amines, elemental sulfur and DMSO as oxidant. This multicomponent decarboxylative transformation consists in a cascade of ring opening, decarboxylative oxidative thioamidation at temperature as low as 50 °C. (Figure presented.).
Cs2CO3-promoted defluorination and functionalization of α-CF3 carbonyl compounds in the presence of: N -, O -, and/or S -nucleophiles
Wu, Yue,Zhang, Bingbing,Zheng, Yinying,Wang, Yuheng,Lei, Xinsheng
, p. 16019 - 16023 (2018/05/22)
A simple, efficient, and mild method for defluorination and functionalization of 3,3,3-trifluoro carbonyl compounds has been developed. In the present method, Cs2CO3 can easily convert α-trifluoromethyl esters, amides, and ketones in
Chemodivergent synthesis of multi-substituted/fused pyrroles via copper-catalyzed carbene cascade reaction of propargyl α-iminodiazoacetates
Zhang, Cheng,Chang, Sailan,Qiu, Lihua,Xu, Xinfang
supporting information, p. 12470 - 12473 (2016/10/24)
A novel cascade reaction of alkynyl-tethered α-iminodiazoacetates has been developed, which provides a general access to both multi-substituted and fused pyrroles in high yields with a broad substrate scope. The γ-imino carbene is proposed as the key intermediate in this divergent reaction and followed by unpresented transformations.
