Selective N-alkylation of isoquinolines, benzazepines and thienopyridines with aromatic aldehydes and naphthols Dedicated to the memory of Professor A. R. Katritzky

Abstract The reactions of 1- or 2-naphthol, benzaldehyde or substituted benzaldehydes with tetrahydroisoquinoline, tetrahydrobenzo[d]azepine, tetrahydrobenzo[c]azepine or tetrahydrothieno[3,2-c]pyridine under solvent-free conditions, allowed a series of tertiary aminonaphthols to be prepared. The reactions were accelerated by the use of microwave irradiation, and the yields were also improved. As an exception, the aminoalkylation of 2-naphthol with 1,2,3,4-tetrahydroisoquinoline in the presence of benzaldehyde led to the parallel N-alkylation and redox alpha-arylation of the tetrahydroisoquinoline in a ratio of 4:1. The reaction of 1-naphthol with 2,3,4,5-tetrahydro-1H-benzo[c]azepine led to the formation of the N-alkylated compound as a single product, illustrating that the reaction route depends on the structures of the cyclic amine and the naphthol.

Electrochemical Approach for Direct C-H Phosphonylation of Unprotected Secondary Amine

Direct alpha-phosphonylation of an unprotected secondary amine in a single step is of practical importance to amino phophophates. However, this protocol is limited due to the high redox barrier of unprotected amine. In this paper, we report C-H phosphonylation of an unprotected secondary amine via an electrochemical approach in the presence of catalytic carboxylate salt. This metal-free and exogenous oxidant-free method furnishes diverse target molecules with satisfactory yield under mild reaction conditions. Successful application of the protocol in a gram-scale experiment demonstrates the potential utility for further functionalization.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 1,2,3,4-Tetrahydroisoquinoline-7-carbonitrile, you can also check out more blogs about149355-52-2

Synthetic Transformations Using Molecular Oxygen-Doped Carbon Materials

Carbon materials like activated carbon (AC) undergo chemisorption with O2 to give species with electron deficiency in the carbon skeleton and negative charge at the oxygen end that upon reaction with PPh3 and benzoic acid afford Ph3P O. Whereas amine donors react with O2-chemisorbed AC and nucleophiles to give dehydrogenatively coupled products in 67-89% yields via the corresponding radical cation and iminium ion intermediates, the reactions using beta-naphthoxide derivatives give the corresponding oxidatively coupled bi-2-naphthol products in 68-95% yields.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3340-78-1 is helpful to your research. Electric Literature of 3340-78-1

Cyclocondensation of 7a-e with hydrazine hydrate produced 6?-(4-chlorophenyl)-3?-[4-(5-substituted aryl-4,5-dihydro- 1H-pyrazol-3-yl)phenyl]-1?H-spiro[cyclohexane-1,2?-thieno- [3,2-d]pyrimidin]-4?(3?H)-ones 8a-e but with hydroxylamine hydrochloride afforded the corresponding isoxazoline derivatives 9a-e. Also, cyclocondensation by thiourea afforded 2-thioxo-1,2- dihydropyrimidin-4-yl)-phenyl-spiro-{cyclohexanethieno[3,2-d] pyrimidin}-4-one derivatives 10a-e. The new compounds were investigated for antimicrobial activity. Compounds 2c, 8b,c, 9b and 10b were the most potent ones against both Gram-negative and Gram-positive bacteria. Compound 8c exhibited higher antifungal activity towards the examined fungi with MIC of 1-2 mumol mL-1 compared to ketoconazole (MIC 2-3 mumol mL-1 ).

Direct Intermolecular C-H Functionalization Triggered by 1,5-Hydride Shift: Access to N-Arylprolinamides via Ugi-Type Reaction

A novel Ugi-type reaction triggered by 1,5-hydride shift has been established, giving access to N-arylprolinamides and related compounds in high atom economy and good yields. This is an example of a two starting material-three component reaction. The benzyl alcohol substrate 1 acts as a dual synthon, which upon treatment with a Br¡ãnsted acid affords iminium ion and water. Nucleophilic attack at the iminium ion by the third component isocyanide, followed by hydrolysis with the endogenic water, gives the Ugi-type reaction products. The reaction proceeds under mild conditions and is tolerable to a broad scope of substrates.

Asymmetric hydrogenation of furan-containing ketones over tartaric acid-modified Raney nickel catalyst

The hydrogenation of beta-keto esters containing a furan unit at the conjugated position to the beta-carbonyl group was carried out over a chiral heterogeneous catalyst, tartaric acid-modified Raney nickel. The hydrogenation first proceeds at the carbonyl to give optically active alcohols, but a simple substrate undergoes further hydrogenation of the furan part to produce a diastereomeric mixture of alcohols having a tetrahydrofuran moiety. This over-reduction was efficiently suppressed by substitutions of a substituent at the furan part. The optical yield at the hydroxy group is in the range of 40-90%.

Prototype Pictet-Spengler reactions catalyzed by superacids. Involvement of dicationic superelectrophiles

The Pictet-Spengler reaction, an acid-catalyzed intramolecular cyclization of intermediate imines of 2-arylethylamine to give 1,2,3,4- tetrahydroisoquinolines, has long been limited to active substrates which bear strongly electron-donating groups such as a methoxy or a hydroxy group on the cyclizing benzene ring. In this paper, we present superacid-catalyzed Pictet-Spengler reactions of imines of 2-phenethylamine, including the prototype Pictet-Spengler reaction of N-methylene-2-phenethylamine, to give the parent and 1-substituted 1,2,3,4-tetrahydroisoquinolines in moderate to high yields. The yields are dependent on the acidity of the media. A linear relationship was found between the rate of the cyclization and the acidity of the reaction media in kinetic studies of N-methylene-2-phenethylamine and related imines, strongly supporting the intervention of an additional protonative activation of the N-protonated imines, that is, the involvement of dicationic superelectrophiles, N,N-diprotonated imines (ammonium- carbenium dications). We further found that the prototype cyclization of the parent N-methylene-2-phenethylamine is also catalyzed by TFA to give 1,2,3,4- tetrahydroisoquinoline in good yield, although the cyclization is significantly slower than that catalyzed by superacids. The prototype Pictet- Spengler cyclization of N-methylene-2-phenethylamine can thus take place both through the monocation (the N-monoprotonated imine) and the dication (the N,N-diprotonated imine), the latter reaction being predominant in superacids.
