I found the field of Chemistry very interesting. Saw the article Rh-Catalyzed C-H Amination/Annulation of Acrylic Acids and Anthranils by Using -COOH as a Deciduous Directing Group: An Access to Diverse Quinolines published in 2020. Name: (E)-2-Methylbut-2-enoic acid, Reprint Addresses Gao, Y (corresponding author), Guangdong Univ Technol, Sch Chem Engn & Light Ind, Guangzhou 510006, Peoples R China.; Hu, XQ (corresponding author), South Cent Univ Nationalities, Sch Chem & Mat Sci, Key Lab Catalysis & Energy Mat Chem, Minist Educ, Wuhan 430074, Hubei, Peoples R China.; Hu, XQ (corresponding author), South Cent Univ Nationalities, Sch Chem & Mat Sci, Hubei Key Lab Catalysis & Mat Sci, Wuhan 430074, Hubei, Peoples R China.. The CAS is 80-59-1. Through research, I have a further understanding and discovery of (E)-2-Methylbut-2-enoic acid
A method for the synthesis of diverse polysubstituted quinolines from readily available acrylic acids and anthranils has been developed. The weakly coordinating -COOH directing group, which can be tracelessly removed in the cascade cyclization, is essential for this reaction. Diverse polysubstituted quinolines were obtained under mild reaction conditions with simple H2O and CO2 as byproducts. More importantly, 1,2,3,4-tetrahydroacridine, which is the core skeleton of tacrine (an Alzheimer’s disease drug), was conveniently synthesized.
