Synthesis of substituted 2-alkylquinolines by visible-light photoredox catalysis was written by Mei, Yousheng;Liu, Jie;Wang, Lei;Li, Pinhua. And the article was included in Organic & Biomolecular Chemistry in 2020.Safety of Ethyl 3-amino-4-methylbenzoate This article mentions the following:
The condensation of anilines RNH2 (R = 2-methyl-4-chlorophenyl, 4-chlorophenyl, 2-methoxyphenyl, etc.) and alkenyl ethers such as ethoxyethene, (E)-1-ethoxyprop-1-ene, (E)-1-ethoxybut-1-ene has been demonstrated by employing visible-light photoredox catalysis. The resulting method enables the synthesis of substituted 2-alkylquinolines I [R1 = Me, Et, Pr; R2 = H, Me, Et; R3 = H, I, Br, etc.; R4 = CN, COOMe, Me, etc.; R5 = H, Br, Me, etc.], II (R6 = H, CF3, Et, OMe; R7 = H, Cl, Br) under mild and simple conditions with good substrate scope and high yields. In the experiment, the researchers used many compounds, for example, Ethyl 3-amino-4-methylbenzoate (cas: 41191-92-8Safety of Ethyl 3-amino-4-methylbenzoate).
Ethyl 3-amino-4-methylbenzoate (cas: 41191-92-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of Ethyl 3-amino-4-methylbenzoate
