With visible-light irradiation, a mild, simple, and efficient metal-free photocatalytic system for the facile construction of sp3-sp 3 C-C bonds between tertiary amines and activated C-H bonds has been achieved. Spectroscopic study and product analysis demonstrate for the first time that photoinduced electron transfer from N-aryl tetrahydroisoquinolines to eosin Y bis(tetrabutylammonium salt) (TBA-eosin Y) takes place to generate TBA-eosin Y radical anion, which can subsequently react with nucleophiles and molecular oxygen. More strikingly, electron spin resonance (ESR) measurements provide direct evidence for the formation of superoxide radical anions (O 2) rather than singlet oxygen (1O 2) during visible-light irradiation. This active species is therefore believed to be responsible for the large rate of acceleration of the aerobic photocatalytic reactions. Light work: With visible-light irradiation (lambda>450 nm), a mild, simple and efficient metal-free photocatalytic system for the facile construction of sp3-sp3 C-C bonds between tertiary amines and activated C-H bonds has been achieved (see scheme). Electron spin resonance measurements offer direct evidence for the formation of superoxide radical anions (O2) during visible-light irradiation. Copyright

A mild and highly efficient metal-free oxidative alpha-cyanation of N-acyl/sulfonyl 1,2,3,4-tetrahydroisoquinolines (THIQs) has been accomplished at an ambient temperature via DDQ oxidation and subsequent trapping of N-acyl/sulfonyl iminium ions with (n-Bu)3SnCN. Employing readily removable N-acyl/sulfonyl groups as protecting groups rather than N-aryl ones enables a wide range of applications in natural product synthesis. The synthetic utility of the method was illustrated using a short and efficient formal total synthesis of (±)-calycotomine in three steps.

New discoveries in chemical research and development in 2021. Electric Literature of 57060-88-5, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 57060-88-5, Name is Methyl 1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride, molecular formula is C11H14ClNO2. In a Article，once mentioned of 57060-88-5

1,2,3,4-Tetrahydroisoquinoline (THIQ) and aryl-substituted derivatives of THIQ are potent inhibitors of the enzyme that catalyzes the formation of epinephrine – phenylethanolamine N-methyltransferase (PNMT, E.C. 2.1.1.28).In previous studies, we found that substitution of the 3-position of THIQ with a methyl group resulted in enhanced activity as an inhibitor for 3-methyl-THIQ (8) with respect to THIQ itself.To more fully delineate this region of the PNMT active site, we have synthesized and evaluated other 3-substituted THIQ analogues that vary in both steric and electronic character.Extension of the methyl side chain in 8 by a single methylene unit results in diminished potency for 3-ethyl-THIQ (13), suggesting that this zone of the active site is spatially compact; furthermore, the region of steric intolerance may be located principally on only “one side” of the 3-position of bound THIQs, since the carbonyl containing (bent) analogues 3-(methoxycarbonyl)-THIQ (10) and 3-(aminocarbonyl)-THIQ (12) are much less capable of forming a strong enzyme-inhibitor dissociable complex compared to straight-chain derivatives possessing a similar steric component.The good activity of 3-(hydroxymethyl)-THIQ (11) as a PNMT inhibitor cannot be explained solely by steric tolerance for this side chain.We believe that an active-site amino acid residue capable of specific (i.e., hydrogen bond) interactions is located in close proximity to the 3-position of bound THIQs and that association of the OH functionality with this active-site residue results in the enhanced in vitro potency of this analogue (Ki = 2.4 muM) compared to that of THIQ (Ki = 10.3 muM).Incorporation of a hydroxymethyl substituent onto the 3-position of the potent PNMT inhibitor 7,8-dichloro-THIQ (SKF 64139, Ki = 0.24 muM) did not result in the same enhancement in inhibitor potency for 17 (Ki = 0.38 muM).This result suggests that simultaneous binding in an optional orientation of the aromatic halogens, secondary amine, and side-chain hydroxyl functionalities to the PNMT active site is not allowed in this analogue.

New research progress on 166591-85-1 in 2021. Synthetic Route of 166591-85-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 166591-85-1, molcular formula is C15H19NO4, introducing its new discovery.

On the basis of a comprehensive analysis of experimental and theoretical IR and vibrational circular dichroism (VCD) spectra, we make suggestions for solvation schemes for carboxylic acids. More specifically, we have studied two chiral carboxylic acids in solvents of different polarity and hydrogen bonding capabilities and verify previously proposed solute-solvent structures for their general applicability. Explicit solvation with acetonitrile-d3 is shown to be most important for carboxylic acid groups directly attached to a stereocenter, while dimethylsulfoxide-d6 should always be considered explicitly in spectra analysis. In order to circumvent the need to consider dimerization with calculations on the full homodimer in nonpolar solvents such as chloroform-d1, we quantitatively evaluate the quality of truncated models. Methanol-d4 is concluded to be the most challenging solvent for VCD studies of carboxylic acids, as the acid strength affects the hydrogen bonding strength to methanol and thus significantly determines the degree and effect of solvation. With the help of matrix-isolation IR spectroscopy, we also characterize the monomeric species of alpha-phenylpropionic acid.
