On August 31, 1979, Kaneko, Chikara; Naito, Toshihiko; Hashiba, Marimi; Fujii, Harue; Somei, Masanori published an article.HPLC of Formula: 65417-22-3 The title of the article was Studies on the N-oxides of π-deficient N-heteroaromatics. Part XXXIII. A novel synthesis of revenine and related alkaloids by means of a photo-rearrangement reaction of 4-alkoxy-2-methylquinoline 1-oxides. And the article contained the following:
Photochem. rearrangement of methylquinoline oxides I (R = Me, allyl, Me2C:CHCH2, HCCCH2) in MeOH gave quinolinones II (R1 = H, R2 = Me; R1 = Me, R2 = H) and methoxyquinolinones III. II (R = Me2C:CHCH2, R1 = Me) is the alkaloid revenine from Rutaccous plants. Chlorination of 2-methyl-4-nitroquinoline oxide by concentrated HCl gave ∼80% 4-chloro-2-methylquinoline oxide, which was treated with ROH containing KOH to give ∼80% I. Photolysis of 4-(methoxycarbonyl)-2-methylquinoline oxide in MeOH gave 25.2% Me indole-3-carboxylate, 15.7% 4-(methoxycarbonyl)-3-methylcarbostyril, 12.3% Me 1-(1,1-dimethoxyethyl)indole-3-carboxylate, 11.5% Me 2-methylindole-3-carboxylate, and 4.3% 4-(methoxycarbonyl)-1-methylcarbostyril. The mechanism of the photorearrangement was discussed. The experimental process involved the reaction of Methyl 2-methyl-1H-indole-3-carboxylate(cas: 65417-22-3).HPLC of Formula: 65417-22-3
