Copper-Catalyzed Remote C(sp3)-H Amination of Carboxamides

Here we report a method for the site-selective intermolecular C(sp3)-H amination of carboxamides by merging transition-metal catalysis and the hydrogen atom transfer strategy. The reaction proceeds through a sequence of favorable single-electron transfer, 1,5-hydrogen atom transfer, and C-N cross-coupling steps, thus allowing access to a series of desired products. This reaction could accommodate a wide diversity of nitrogen nucleophiles as well as demonstrate excellent chemoselectivity and functional group compatibility.

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.HPLC of Formula: C9H10ClN, you can also check out more blogs about33537-99-4

P-GP RADIOTRACERS FOR IMAGING AS BIOMARKER INVOLVED IN ONSET OF NEURODEGENERATIVE DISEASES

The invention includes a new class of radiolabeled compounds of formula I able to bind P-glycoprotein with high affinity and selectivity. The protein prevents accumulation in the brain of a wide range of drugs and, changes in P-gp expression and function, are also believed to occur in several neurological disorder, such as Alzheimer’s disease (AD). Indeed, it is widely reported that decreased expression of P- gp and/or activity at the BBB level could cause accumulation of I3- amyloid plaques, the main hallmark of AD onset. 13-amyloid is a P-gp substrate, and these results support the importance of P-gp in the clearance of 13-amyloid peptide from brain parenchyma. For this reason, P-gp can be considered a useful biomarker for the early diagnosis of neurodegeneration. There is considerable interest in the development of P-gp PET radiotracers for imaging expression and function of P-gp.

Graphite-supported gold nanoparticles as efficient catalyst for aerobic oxidation of benzylic amines to imines and N-substituted 1,2,3,4- tetrahydroisoquinolines to amides: Synthetic applications and mechanistic study

Selective oxidation of amines using oxygen as terminal oxidant is an important area in green chemistry. In this work, we describe the use of graphite-supported gold nanoparticles (AuNPs/C) to catalyze aerobic oxidation of cyclic and acyclic benzylic amines to the corresponding imines with moderate-to-excellent substrate conversions (43-100%) and product yields (66-99%) (19 examples). Oxidation of N-substituted 1,2,3,4- tetrahydroisoquinolines in the presence of aqueous NaHCO3 solution gave the corresponding amides in good yields (83-93%) with high selectivity (up to amide/enamide=93:4) (6 examples). The same protocol can be applied to the synthesis of benzimidazoles from the reaction of o-phenylenediamines with benzaldehydes under aerobic conditions (8 examples). By simple centrifugation, AuNPs/C can be recovered and reused for ten consecutive runs for the oxidation of dibenzylamine to N-benzylidene(phenyl) methanamine without significant loss of catalytic activity and selectivity. This protocol “AuNPs/C+O 2” can be scaled to the gram scale, and 8.9 g (84% isolated yield) of 3,4-dihydroisoquinoline can be obtained from the oxidation of 10 g 1,2,3,4-tetrahydroisoquinoline in a onepot reaction. Based on the results of kinetic studies, radical traps experiment, and Hammett plot, a mechanism involving the hydrogen-transfer reaction from amine to metal and oxidation of M-H is proposed.

Synthesis of substituted tetrahydroisoquinolines by lithiation then electrophilic quench

Substituted N-tert-butoxycarbonyl (Boc)-1,2,3,4-tetrahydroisoquinolines were prepared and treated with n-butyllithium in THF at -50 C to test the scope of the metallation and electrophilic quench. The lithiation was optimised by using in situ ReactIR spectroscopy and the rate of rotation of the carbamate was determined. The 1-lithiated intermediates could be trapped with a variety of electrophiles to give good yields of 1-substituted tetrahydroisoquinoline products. Treatment with acid or reduction with LiAlH4 allows conversion to the N-H or N-Me compound. The chemistry was applied to the efficient total syntheses of the alkaloids (¡À)-crispine A and (¡À)-dysoxyline.

Chemoselective Strategy for the Direct Formation of Tetrahydro-2,5-methanobenzo[c]azepines or Azetotetrahydroisoquinolines via Regio- and Stereoselective Reactions

The present study reports regio- and highly diastereoselective preparative methods for the synthesis of versatile alkaloid-type compounds from oxiranylmethyl tetrahydroisoquinolines. 2,5-Methanobenzo[c]azepines or azetidine-fused heterocycles were synthesized in tandem reactions depending on the absence or presence of a BF3 co-reagent. A high functional group tolerance has also been demonstrated. DFT calculations with an explicit solvent model confirmed the proposed reaction mechanisms and the role of kinetic controls on the stereochemical outcome of the reported new methods.
