Facile synthesis of vicinal diamines via oxidation of N-phenyltetrahydroisoquinolines with DDQ

The oxidation of N-phenyltetrahydroisoquinolines occurs rapidly with DDQ. Under ambient conditions and in the presence of nitromethane, the corresponding beta-nitroamine derivatives are isolated in good to excellent yields. Variation in the electronic nature of the isoquinoline and the N-phenyl substituent showed that a broad range of substituents are tolerated, with electronic communication between the isoquinoline aromatic ring and the C1 carbon being stronger than with the N-aryl ring. Reduction of the beta-nitroamines to the corresponding novel chiral vicinal diamines are straightforward. Examination of the reaction by 1H NMR spectroscopy suggested that the reaction proceeds via an iminium ion, which then reacts with nitromethane upon work-up. This information was used to shorten the required reaction time.

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 3340-78-1 is helpful to your research. Reference of 3340-78-1

Highly efficient heterogeneous aerobic oxidative C-C coupling from C sp3-H bonds by a magnetic nanoparticle-immobilized bipy-gold(iii) catalyst

A highly efficient heterogeneous cross-dehydrogenative coupling (CDC) of tertiary amines with nitroalkanes and various unmodified ketones was achieved by using a magnetic nanoparticle-immobilized bipy-gold(iii) complex as catalyst and air as the sole oxidant to afford the corresponding C-C coupling products in good to excellent yields under mild reaction conditions. The new heterogeneous gold catalyst can easily be separated from the reaction mixture by applying an external magnet and can be recycled at least ten times without a significant loss of activity.

A series of 1-aryl-1,2,3,4-tetrahydroisoquinoline and 8-methyl-1-aryl-1,2,3,4-tetrahydroisoquinoline derivatives was evaluated for affinity to the PCP binding site of the NMDA receptor complex. The (S)-configurated tetrahydroisoquinoline derivative (S)-4e¡¤HCl bearing a 2-methylphenyl substituent in position 1 of the heterocyclic ring system and a methyl group in position 8 was found to exhibit the highest affinity among the derivatives with a Ki-value of 0.0374?muM. In addition, this compound shows a remarkable enantioselectivity of binding by being almost 90 times more potent than the corresponding (R)-enantiomer (R)-4e¡¤HCl.

Diastereoselective addition of chiral (2-lithiophenyl)acetaldehyde acetals to various imines as key step in the asymmetric synthesis of 1- aryltetrahydroisoquinolines, part 4

A novel asymmetric synthesis of 1-aryl-1,2,3,4-tetrahydroisoquinolines has been developed. The key step in this synthesis is the diastereoselective addition of homochiral (2-lithiophenyl)acetaldehyde acetals to the sulfonylimine 25 and to the arylimines 28 and 31. The best diastereoselectivity is obtained by addition of the bis(2-methoxypropan-2- yl)-substituted 1,3-dioxolane 6e to benzylidene-p-anisidine (31) with an HPLC-determined diastereomeric ratio 32c/33c = 92.1:7.9. The N-tosyl and the N-(4-methoxyphenyl) groups of the addition products 26d, 27d, 32c, and 33c are cleaved with sodium in liquid ammonia and ammonium cerium(IV) nitrate, respectively, to yield the primary amines 35 and 36. The acid-catalysed cyclization of the sulfonamides 26d and 27d and the carbamates 37 and 38, prepared from 35 and 36, leads to the enantiomerically pure dihydroisoquinolines 40 and 41, respectively. During the cyclization of the sulfonamides 26d, 27d and the carbamates 37, 38 the chiral auxiliary – the diol 39 – is cleaved unchanged and can be recovered in good yields.

Design and Synthesis of Potent, Selective Inhibitors of Protein Arginine Methyltransferase 4 against Acute Myeloid Leukemia

PRMT4 is a type I protein arginine methyltransferase and plays important roles in various cellular processes. Overexpression of PRMT4 has been found to be involved in several types of cancers. Selective and in vivo effective PRMT4 inhibitors are needed for demonstrating PRMT4 as a promising therapeutic target. On the basis of compound 6, a weak dual PRMT4/6 inhibitor, we constructed a tetrahydroisoquinoline scaffold through a cut-and-sew scaffold hopping strategy. The subsequent SAR optimization efforts employed structure-based approach led to the identification of a novel PRMT4 inhibitor 49. Compound 49 exhibited prominently high potency and selectivity, moderate pharmacokinetic profiles, and good antitumor efficacy in acute myeloid leukemia xenograft model via oral administration, thus demonstrating this compound as a useful pharmacological tool for further target validation and drug development in cancer therapy.
