Visible-light-induced direct alpha-C(sp3)-H thiocyanation of tertiary amines

Visible-light-induced, eosin Y catalyzed aerobic oxidative alpha-C(sp3)-H thiocyanation of tertiary amines is reported. The reaction proceeds through visible-light-induced in situ generation of the iminium ion followed by attack of -SCN nucleophile. This is the first example of visible-light-initiated formation of C(sp3)-S bond employing organo-photoredox catalysis. Mild reaction conditions and use of air and visible light as the greenest and sustainable reagents at room temperature are the salient features of the protocol.

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 1745-07-9 is helpful to your research. 1745-07-9

Substituted 2-(1,2,3,4-tetrahydroisoquinoline)-butyl derivatives of azaspiro[4.5]decane-7,9-dione and phthalimide as new 5-HT1a and 5-HT2a receptor ligands

Two series of 2-butyl-8-azaspiro[5,4]decane-7,9-dione (a) and N-phthalimidobutyl (b) derivatives of 1,2,3,4-tetrahydroisoquinoline (THIQ) were synthesized. The impact of substituent variations in the aromatic part of the THIQ moiety on 5-HT1A and 5-HT2A receptor affinities, as well as in vivo functional properties of the investigated compounds are discussed. It was found that those modifications improved 5-HT2A receptor affinity, but also slightly reduced the binding affinity for 5-HT1A receptors (in comparison with the unsubstituted THIQ derivatives 3a and 3b). The most active compound (8-Br,5-OCH3-THIQ – 8a) showed features of a 5-HT1A (postsynaptic)/5-HT2A receptor antagonist. Additionally, all chloro derivatives with high and equal affinity for 5-HT1A receptors revealed different functional properties, i.e. an agonistic activity of presynaptic 5-HT1A receptors (4a) and a partial agonistic activity of postsynaptic 5-HT1A receptors (4a, 6a) or an antagonistic activity of postsynaptic ones (5a).

PROCESS FOR PREPARATION OF ENANTIOMERICALLY PURE (S)-1-PHENYI-1,2,3,4- TETRAHYDROISOQUINOLINE

Process for preparation of (S)-1 -phenyl-1, 2,3, 4-tetrahydroisoquinoline is characterized in that 1-phenyl-1,2,3, 4-tetrahydroisoquinoline is reacted with D-(-)- tartaric acid in a solvent system consisting of methanol and water, preferably at 3.3:1 to 1 :1 volume ratio, the crystallization mixture is left for crystallization and (S)-1-phenyl-1,2,3, 4-tetrahydroisoquinoline is released from obtained crystalline diastereoisomeric salt according to standard procedures.

Remote Effects Modulating the Spin Equilibrium of the Resting State of Cytochrome P450cam – An Investigation Using Active Site Analogues

The crystal structure of the resting state of cytochrome P450 cam (CYP101), a heme thiolate protein, shows a cluster of six water molecules in the substrate binding pocket, one of which is coordinating to iron(III) as sixth ligand. The resting state is low-spin and changes to high-spin when substrate camphor binds and H2O is removed. In contrast to the protein, previously synthesised enzyme models such as H 2O-FeIII(porph)(ArS-) were shown to be purely high-spin. Iron(S-)porphyrins with different distal sites mimicking proposed remote effects have been prepared and studied by cw-EPR. The results indicate that the low-spin of the resting state of P450cam is due to the fact that the water molecule coordinating to iron has an OH –like character because of hydrogen bonding and polarisation of the water cluster, respectively.

A versatile C-H functionalization of tetrahydroisoquinolines catalyzed by iodine at aerobic conditions

A versatile aerobic catalytic system (I2 and O2/TBHP) for C-H functionalization is reported. This CDC (cross-dehydrogentive coupling) reaction is compatible with a large number of nucleophiles and is performed under ambient reaction conditions. The scope of the metal-free CDC is illustrated by synthesizing a variety of functionalized tetrahydroisoquinolines and N,N-dimethylaniline. The highlight of the method is a Friedel-Crafts reaction of phenols and indole with tertiary amines.

Photo-induced Decarboxylative Heck-Type Coupling of Unactivated Aliphatic Acids and Terminal Alkenes in the Absence of Sacrificial Hydrogen Acceptors

1,2-Disubstituted alkenes such as vinyl arenes, vinyl silanes, and vinyl boronates are among the most versatile building blocks that can be found in every sector of chemical science. We herein report a noble-metal-free method of accessing such olefins through a photo-induced decarboxylative Heck-type coupling using alkyl carboxylic acids, one of the most ubiquitous building blocks, as the feedstocks. This transformation was achieved in the absence of external oxidants through the synergistic combination of an organo photo-redox catalyst and a cobaloxime catalyst, with H2 and CO2 as the only byproducts. Both control experiments and DFT calculations supported a radical-based mechanism, which eventually led to the development of a selective three-component coupling of aliphatic carboxylic acids, acrylates, and vinyl arenes. More than 90 olefins across a wide range of functionalities were effectively synthesized with this simple protocol.

Synthesis of Functionalized Cyclopropanes from Carboxylic Acids by a Radical Addition?Polar Cyclization Cascade

Herein, we describe the development of a photoredox-catalyzed decarboxylative radical addition?polar cyclization cascade approach to functionalized cyclopropanes. Reductive termination of radical?polar crossover reactions between aliphatic carboxylic acids and electron-deficient alkenes yielded carbanion intermediates that were intercepted in intramolecular alkylations with alkyl chlorides appended to the alkene substrate. The mild conditions, which make use of a readily available organic photocatalyst and visible light, were demonstrated to be amenable to a broad range of structurally complex carboxylic acids and a wide variety of chloroalkyl alkenes, demonstrating exquisite functional group tolerance.

Catalytic asymmetric ¡À-acylation of tertiary amines mediated by a dual catalysis mode: N-heterocyclic carbene and photoredox catalysis

Cross-coupling reactions are among the most widely utilized methods for C-C bond formation; however, the requirement of preactivated starting materials still presents a major limitation. Methods that take direct advantage of the inherent reactivity of the C-H bond offer an efficient alternative to these methods, negating the requirement for substrate preactivation. In this process, two chemically distinct activation events culminate in the formation of the desired C-C bond with loss of H2 as the only byproduct. Herein we report the catalytic asymmetric ¡À-acylation of tertiary amines with aldehydes facilitated by the combination of chiral N-heterocyclic carbene catalysis and photoredox catalysis.
