In 2019,Angewandte Chemie, International Edition included an article by Chen, Jie; Guo, Pan; Zhang, Jianguo; Rong, Jiaxin; Sun, Wangbin; Jiang, Yaojia; Loh, Teck-Peng. Name: N,N-Dimethylformamide Dimethyl Acetal. The article was titled 《Synthesis of Functionalized α-Vinyl Aldehydes from Enaminones》. The information in the text is summarized as follows:
An efficient RhII-catalyzed synthesis of functionalized α-vinyl aldehydes with high E/Z stereoselectivity was developed. The reaction mediates the cyclopropanation of enaminones with vinyl carbenoids that are generated from cyclopropenes in situ to give the aminocyclopropane intermediates. Selective C-C bond cleavage of the cyclopropane intermediates leads to formation of α-vinyl aldehyde derivatives with high E/Z selectivity. This method proceeds at room temperature under very mild reaction conditions and works with a broad substrate scope.N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Name: N,N-Dimethylformamide Dimethyl Acetal) was used in this study.
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. Reduction of nitro compounds, RNO2, by hydrogen or other reducing agents produces primary amines cleanly (i.e., without a mixture of products), but the method is mostly used for aromatic amines because of the limited availability of aliphatic nitro compounds. Reduction of nitriles and oximes (R2C=NOH) also yields primary amines.Name: N,N-Dimethylformamide Dimethyl Acetal
