A noncentrosymmetric coordination polymer based on the benzophenone-3,3?-disulfonyl-4,4?-dicarboxylate ligand exhibiting second-harmonic-generation responses

A 3D coordination polymer [CdK6(mu2-H2O)2(BODSDC)2(H2O)]n (1) based on the novel benzophenone-3,3?-disulfonyl-4,4?-dicarboxylate (BODSDC4?) ligand was synthesized and structurally characterized. The carboxylate and sulfonate groups of the organic ligands as well as the bridging water molecules connect the Cd2+ and K+ ions to produce a 2D layer, which is linked by the benzophenone moieties to give a 3D pillared framework. Compound 1 crystallizes in an acentric space group of Cc and has a large second-harmonic-generation (SHG) response of 1.3 times that of potassium dihydrogen phosphate (KDP) in the particle size of 25?210 mum. Further SHG measurements revealed that the material is type-I phase-matchable. The observed SHG efficiency is associated with the unsymmetrical geometry of the organic ligand and the distorted coordination polyhedrons of metal centers.

Regio- and chemoselective Csp3-H arylation of benzylamines by single electron transfer/hydrogen atom transfer synergistic catalysis

We present a highly regio- and chemoselective Csp3-H arylation of benzylamines mediated by synergy of single electron transfer (SET) and hydrogen atom transfer (HAT) catalysis. Under well precedented SET catalysis alone, the arylation reaction of N,N-dimethylbenzylamine proceeded via aminium radical cation formation and selectively targeted the N-methyl group. In contrast, addition of PhC(O)SH as a HAT catalyst precursor completely switched the regioselectivity to Csp3-H arylation at the N-benzylic position. Measurement of oxidation potentials indicated that the conjugate base of PhC(O)SH is oxidized in preference to the substrate amine. The discovery of the thiocarboxylate as a novel HAT catalyst allowed for the selective generation of the sulfur-centered radical, so that the N-benzyl selectivity was achieved by overriding the inherent N-methyl and/or N-methylene selectivity under SET catalysis conditions. While visible light-driven alpha-C-H functionalization of amines has mostly been demonstrated with aniline derivatives and tetrahydroisoquinolines (THIQs), our method is applicable to a variety of primary, secondary and tertiary benzylamines for efficient N-benzylic C-H arylation. Functional group tolerance was high, and various 1,1-diarylmethylamines, including an alpha,alpha,alpha-trisubstituted amine, were obtained in good to excellent yield (up to 98%). Importantly, the reaction is applicable to late-stage functionalization of pharmaceuticals.

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.Safety of 2-Methyl-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about1612-65-3

A highly efficient method to fulfil the three-component C1 alkynylation of tetrahydroisoquinolines catalyzed by silver acetate was developed. This method features excellent regioselectivity and mild reaction conditions, is oxidant free, and can be performed in air. The power of this methodology was demonstrated by the rapid construction of the core structure of the natural product (tetrahydroberberine).

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.

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.

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.
