Compound: 2-Amino-5-chlorobenzaldehyde, is researched, Molecular C7H6ClNO, CAS is 20028-53-9, about Yb(OTf)3-Mediated Annulation of Cyclopropane-1,1-dicarbonitriles with 2-Aminobenzaldehydes for Synthesis of Polysubstituted Quinolines. Author is Wan, Xinyi; Wang, Shan; Wu, Chengjun; Gan, Jianbo; Wang, Cunde.
A Yb(OTf)3-mediated annulation of cyclopropane-1,1-dicarbonitriles and 2-aminobenzaldehydes for the synthesis of polysubstituted quinolines in generally good yields was investigated. In the cascade reaction, the protocol includes ring opening, intermol. nucleophilic addition, intramol. nucleophilic addition, and de-malononitrile aromatization, in which the malononitrile group served as a deciduous directing group mediated by Yb(OTf)3.
The article 《Yb(OTf)3-Mediated Annulation of Cyclopropane-1,1-dicarbonitriles with 2-Aminobenzaldehydes for Synthesis of Polysubstituted Quinolines》 also mentions many details about this compound(20028-53-9)SDS of cas: 20028-53-9, you can pay attention to it, because details determine success or failure
