Methyl isoquinoline-3-carboxylate (cas: 27104-73-0) belongs to isoquinoline derivatives. Being an analog of pyridine, isoquinoline is a weak base, with a pKa of 5.14. It protonates to form salts upon treatment with strong acids, such as HCl. It forms adducts with Lewis acids, such as BF3.Computed Properties of C11H9NO2

Diphenylselenium bistrifluoroacetate: a new reagent for biomimetic oxidations of amines and amino acids was written by Marino, Joseph P.;Larsen, Robert D. Jr.. And the article was included in Journal of the American Chemical Society in 1981.Computed Properties of C11H9NO2 This article mentions the following:

The mild two electron oxidation of quinolines I [R = MeO; R1 = H, Me, CO2H, 3,4-(MeO)2C6H3CH2; R2-R4 = H] and carbolines II (R5 = H, Me; R6, R7 = H; R8 = H, CO2Me) by Ph2Se(OCOCF3)2 (III) gave the corresponding I (R3R4 = bond) and II (R6R7 = bond) in high yields. Iminium cations were prepared regiospecifically when I (R = MeO, H; R1, R3 = H; R2 = H, CO2Me; R4 = Me) were treated with III. I (R = R1 = R3 = R4 = H; R2 = CO2H, CO2Me) were oxidatively decarboxylated by III to give the corresponding isoquinolines. The mechanistic rationale for these oxidations was discussed based on the formation of an intermediate azulene. In the experiment, the researchers used many compounds, for example, Methyl isoquinoline-3-carboxylate (cas: 27104-73-0Computed Properties of C11H9NO2).
