Ke, Lei published the artcileCatalytic Selective Oxidative Coupling of Secondary N-Alkylanilines: An Approach to Azoxyarene, Formula: C11H12O3, the main research area is azoxyarene preparation anticancer catalyst oxidative coupling secondary alkylaniline.

Azoxyarenes are among important scaffolds in organic mols. Direct oxidative coupling of primary anilines provides a concise fashion to construct them. However, whether these scaffolds can be prepared from secondary N-alkylanilines is not well explored. Here, the authors present a catalytic selective oxidative coupling of secondary N-alkylaniline to afford azoxyarene with tungsten catalyst under mild conditions. In addition, azoxy can be viewed as a bioisostere of alkene and amide. Several “”azoxyarene analogs”” of the corresponding bioactive alkenes and amides showed comparable promising anticancer activities.

DiPucchio, Rebecca C. published the artcileExploiting Natural Complexity: Synthetic Terpenoid-Alkaloids by Regioselective and Diastereoselective Hydroaminoalkylation Catalysis, Application In Synthesis of 5961-59-1, the main research area is regioselective diastereoselective hydroaminoalkylation limonene pinene aniline tantalum urea catalyst.

We report a catalytic and atom-economic approach for the addition of N-Me groups to unactivated alkene-containing terpenes to generate a library of synthetic terpenoid-alkaloids. This catalysis was accomplished using Ta(CH2SiMe3)3Cl2 in combination with a new chiral ureate salt, I, for highly chemo-, regio-, and diastereoselective hydroaminoalkylation reactions. The desired products are easily isolated and purified from unreacted starting materials to give aminated terpenes, e.g., II, in one catalytic step. Starting material enantiopurity is completely retained and stereoselective catalysis results give enantiopure products. Absolute stereochem. was determined by X-ray crystallog. and is consistent with regio- and stereoselective alkene insertion into a catalytically active tantallaziridine intermediate.

Li, Ziyi published the artcileDynamic Covalent Reactions Controlled by Ring-Chain Tautomerism of 2-Formylbenzoic Acid, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is hydroxy isobenzofuroalc preparation; alc hydroxy isobenzofurone dynamic covalent reaction; isobenzofurothiol hydroxy preparation; thiol hydroxy isobenzofurone dynamic covalent reaction; isobenzofuroamine hydroxy preparation; amino hydroxy isobenzofurone dynamic covalent reaction.

The development of dynamic covalent reactions (DCRs) of common N-, O-, and S-mononucleophiles by controlling ring-chain tautomerism of 2-formylbenzoic acid was demonstrated. The regulation of distinct dual reactivity of interconverting open aldehyde and cyclic hemiacetal forms, the thermodn. stabilization through chelation and delocalization, as well as the kinetic effect resulting from neighboring group participation, enabled the realization of DCRs of a broad range of alcs. ROH (R = Et, cyclohexyl, Bn, etc.), thiols NHRSH, primary amines RNH2, and secondary amines R1NH (R1 = diethylaminyl, piperidin-1-yl, (4-methoxyphenyl)(methyl)aminyl, etc.) exhibiting high efficiency and fast equilibrium The dynamic nature of the system was verified through component exchange, and the switch of DCRs was achieved through the manipulation of substrate selectivity. The investigation of mechanism shed insights on the dependence of reaction pathways on nucleophiles, laying the foundation for future design and application.

Go, Su Yong published the artcileA Unified Synthetic Strategy to Introduce Heteroatoms via Electrochemical Functionalization of Alkyl Organoboron Reagents, HPLC of Formula: 151-10-0, the main research area is organotrifluoroborate preparation electrochem oxidation nucleophilic addition alc ester indole; chiral fluorooxoicosahydropicenyl acetate preparation crystal structure; mol structure chiral fluorooxoicosahydropicenyl acetate; ether sterically congested electrochem preparation; ester sterically congested electrochem preparation; indole sterically congested electrochem preparation; kinetics electrochem oxidation organotrifluoroborate nucleophilic addition alc ester.

Based on systematic electrochem. anal., an integrated synthetic platform of C(sp3)-based organoboron compounds was established for the introduction of heteroatoms. The electrochem. mediated bond-forming strategy is highly effective for the functionalization of sp3-hybridized C atoms with significant steric hindrance. Also, virtually all the nonmetallic heteroatoms could be used as reaction partners using one unified protocol. The observed reactivity stems from the two consecutive single-electron oxidations of the substrate, which eventually generates an extremely reactive carbocation as the key intermediate. The detailed reaction profile could be elucidated through multifaceted electrochem. studies. Ultimately, a new dimension in the activation strategies for organoboron compounds was accomplished through the electrochem. driven reaction development.
