Organocatalytic asymmetric arylation of indoles enabled by azo groups

Arylation is a fundamental reaction that can be mostly fulfilled by electrophilic aromatic substitution and transition-metal-catalysed aryl functionalization. Although the azo group has been used as a directing group for many transformations via transition-metal-catalysed aryl carbon-hydrogen (C-H) bond activation, there remain significant unmet challenges in organocatalytic arylation. Here, we show that the azo group can effectively act as both a directing and activating group for organocatalytic asymmetric arylation of indoles via formal nucleophilic aromatic substitution of azobenzene derivatives. Thus, a wide range of axially chiral arylindoles have been achieved in good yields with excellent enantioselectivities by utilizing chiral phosphoric acid as catalyst. Furthermore, highly enantioenriched pyrroloindoles bearing two contiguous quaternary chiral centres have also been obtained via a cascade enantioselective formal nucleophilic aromatic substitution-cyclization process. This strategy should be useful in other related research fields and will open new avenues for organocatalytic asymmetric aryl functionalization.

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 1075-35-0 is helpful to your research. SDS of cas: 1075-35-0

Indol-1-yl acetic acids as peroxisome proliferator-activated receptor agonists: Design, synthesis, structural biology, and molecular docking studies

A series of novel indole-based PPAR agonists is described leading to discovery of 10k, a highly potent PPAR pan-agonist. The structural biology and molecular docking studies revealed that the distances between the acidic group and the linker, when a ligand was complexed with PPARgamma protein, were important for the potent activity. The hydrophobic tail part of 10k makes intensive hydrophobic interaction with the PPARgamma protein resulting in potent activity.

Synthesis and preliminary cytotoxicity study of glucuronide derivatives of CC-1065 analogues

Glucuronide derivatives of CBI-bearing CC-1065 analogues have been synthesized, and their cytotoxicities tested against U937 leukemia cells. The new compounds show potent antitumor activity in vitro. Compounds 1 and 2, and their corresponding glucuronides 3 and 4 have IC50 values of 0.6, 0.1, 1.4 and 0.6 nM, respectively. Glucuronide 3 is approximately 2-fold less toxic than its hydroxyl counterpart 1, and glucuronide 4 is approximately 6-fold less toxic than its hydroxyl counterpart 2. Glucuronides 3 and 4 may have limited use in the ADEPT approach. However, they may be used as antitumor agents in a conventional way.

Synthesis and Dopamine Agonist Properties of (+/-)-trans-3,4,4a,10b-Tetrahydro-4-propyl-2H,5H-<1>benzopyrano<4,3-b>-1,4-oxazin-9-ol and Its Enantiomers

The dopamine agonist profile of (+/-)-trans-3,4,4a,10b-tetrahydro-4-propyl-2H,5H-<1>benzopyrano<4,3-b>-1,4-oxazin-9-ol (16a) and its enantiomers (16b-c) was examined.Racemic 16a exhibited moderate affinity for the dopamine (DA) D2 receptor labeled with the DA antagonist ligand <3H>haloperidol and moderate in vivo activity; it attenuated gamma-butyrolactone-stimulated DA synthesis, decreased DA neuronal firing of substantia nigra DA neurons, and inhibited exploratory locomotor activity in rats, a profile consistent with a DA autoreceptor agonist mechanism of action.The (+)-enantiomer 16b possessed greater DA receptor affinity with the agonist ligand <3H>-N-propylnorapomorphine then with the antagonist ligand.In rats it potently inhibited DA synthesis and neuronal firing and also inhibited exploratory locomotion.The (-)-enantiomer, on the other hand, did not have significant activity in any of these tests.This profile indicates that like many other rigid DA agonists, the dopaminergic activity resides in one enantiomer, in this case the (+)-enantiomer 16b.On the basis of single-crystal X-ray analysis of a key intermediate, the absolute configuration of 16b was found to be 4aR, 10bR.

ORGANIC NITROSONIUM SALTS. II. STABILITY STUDIES AND OXIDATIONS OF SOME INDOLE DERIVATIVES

The stabilities of various salts of the 2,2,6,6-tetramethylpiperidine-1-oxonium ion were studied. 2,2,6,6-Tetramethylpiperidine-1-oxonium tetrafluoroborate was shown to react with 1,2,3,4-tetrahydrocarbazole (1-H-2,3,4,9-tetrahydrocarbazole) to give, in the presence of water, 4-keto-1,2,3,4-tetrahydrocarbazole in good yield.Under the same conditions, cyclopentindole and cycloheptindole gave the corresponding keto derivatives.In the absence of water, the oxidation of tetrahydrocarbazole gave a mixture of dimers, probably derived from the Diels-Alder self condensation of 1-H-2,3-dihydrocarbazole.The condensation is reversible and, in acid, the dimer mixture gives a salt of 1-H-2,3-dihydrocarbazole which can be reduced with sodium borohydride to give back tetrahydrocarbazole.
