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, HCCCH2) 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

Hsu, Shih-Fan; Ko, Chih-Wei; Wu, Yao-Ting published an article in 2011, the title of the article was Cobalt-Catalyzed Carbon-Carbon Bond Formation: Synthesis and Applications of Enantiopure Pyrrolidine Derivatives[1].Computed Properties of 79815-20-6 And the article contains the following content:

In the presence of cobalt catalysts and tetramethylethylenediamine (TMEDA), the iodine atom in (S)-2-(iodomethyl)pyrrolidines was replaced by an aryl or an alkynyl group from the corresponding Grignard reagent, and the coupling products were obtained in good to excellent yields (16 examples; 75-94% yields). The scope and limitations of this protocol were examined The stereochem. of the pyrrolidines was unaffected by the reaction conditions. The coupling products are important building blocks of phenanthroindolizidine alkaloids. Palladium-catalyzed formal [4+2] cycloaddition of 2,2′-diiodobiphenyl with the thus-generated (S)-2-(3-trimethylsilyl-2-propynyl)pyrrolidine gave a good yield of the desilylated phenanthrene, which was then converted into unnatural (+)-(S)-tylophorine by the Pictet-Spengler cyclization. The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Computed Properties of 79815-20-6

Jiang, Xue; Wang, Chao; Wei, Yawen; Xue, Dong; Liu, Zhaotie; Xiao, Jianliang published an article in 2014, the title of the article was A General Method for N-Methylation of Amines and Nitro Compounds with Dimethylsulfoxide.SDS of cas: 52537-00-5 And the article contains the following content:

DMSO reacts with a broad range of amines in the presence of formic acid, providing a novel, green and practical method for amine methylation. The protocol also allows the one-pot transformation of aromatic nitro compounds into di-Me amines in the presence of a simple iron catalyst. A mechanistic study indicated that the synthesis of the target compounds was achieved by a methylene group transfer from DMSO to an amine, formation of an imine intermediate and subsequent reduction of this imine by formic acid. A reaction of 2-[2-(1,3-benzodioxolyl)ethyl]-1,2,3,4-tetrahydroquinoline with DMSO/HCO2H gave 2-[2-(1,3-benzodioxolyl)ethyl]-1,2,3,4-tetrahydro-1-(methyl)quinoline (allocuspareine, galipinine).
