Enantioselective Friedel-Crafts Alkylation Reaction of Indoles with alpha-Trifluoromethylated beta-Nitrostyrenes Catalyzed by Chiral BINOL Metal Phosphate

An efficient enantioselective Friedel-Crafts alkylation reaction of indoles with alpha-CF3-substituted beta-nitrostyrenes is disclosed. The key to success is the use of a chiral calcium BINOL bis(phosphate) complex as a Lewis acid catalyst. The reaction gives access to a wide variety of optically active indoles bearing trifluoromethylated all-carbon quaternary stereocenter (up to 20 examples) in high yields (up to 99%) with excellent enantioselectivities (up to 98%) under mild reaction conditions. Non activated alpha-alkyl-beta-nitrostyrenes also participated in the Friedel-Crafts alkylation reaction successfully.

Covalent or Non-Covalent? A Mechanistic Insight into the Enantioselective Bronsted Acid Catalyzed Dearomatization of Indoles with Allenamides

The reaction mechanism of the enantioselective Bronsted acid catalyzed dearomatization of C(2),C(3)-disubstituted indoles with allenamides is investigated by means of density functional theory (DFT) calculations and ESI-MS analysis. The first step of the process (rate-determining step) is the formation of a covalent adduct between allenamide and the chiral organo-promoter. The resulting chiral alpha-amino allylic phosphate undergoes dearomative condensation with indoles. In the first step, the indole moiety remains bonded to the catalyst through strong hydrogen contacts. It can take on two different orientations that make the Re or Si prochiral face available to the subsequent electrophilic attack of allenamide. The attack on the indole faces originates two reaction paths leading to different stereoisomeric products, which differ in the configuration of the new stereocenter at the C3-indole position.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 147-94-4 help many people in the next few years. COA of Formula: C9H13N3O5.

Efficient synthesis of cyano-containing multi-substituted indoles catalyzed by lipase

Background: Indoles are important bioactive compounds that have been extensively studied in organic chemistry. In this work, a green and efficient process for the synthesis of Indoles from 1,3-diketones with fumaronitrile was developed. Results: Under optimal conditions (1,3-diketones (0.5 mmol), fumaronitrile (1 mmol), water (2 ml), lipase (15 mg), 30 degrees C, 24 h), high yields and satisfactory regioselectivity of cyano-containing multi-substituted indoles could be obtained when CRL (C. rugosa lipase) was used as the catalyst. Conclusion: This enzymatic method demonstrates the great potential for the synthesis of indoles and extends the application of enzyme in organic synthesis.

TBHP Mediated Substrate Controlled Oxidative Dearomatization of Indoles to C2/C3-Quaternary Indolinones

Oxidative dearomatization of indoles with 70% aqueous tert-butylhydroperoxide (TBHP) in the absence of any metal salts/organic solvents gave the corresponding C2/C3-quaternary indolinones under open-air reaction conditions. The nature of substituent on the indole nitrogen dictates the type of product formed in these reactions. Free (NH)-indoles gave C2-quaternary indolinone derivatives whilst (NR)-indoles yielded C3-quaternary indolinones as the major product. Moreover, the addition of an excess amount of TBHP also facilitated the one-pot transformation of (NR)-indoles to the corresponding isatin derivatives.

A series of novel indole derivatives were synthesized and evaluated for their antiproliferative activity against three selected cancer cell lines (MGC803, EC-109 and PC-3). Among these analogues, 2-(5-methoxy-1H-indol-1-yl)-N-(4-methoxybenzyl)-N-(3,4,5-trimethoxyphenyeacetamide (V7) showed the best inhibitory activity against MGC803 cells with an IC50 value of 1.59 mu M.

A multicomponent reaction to design antimalarial pyridyl-indole derivatives: Synthesis, biological activities and molecular docking

Using fragment-based design strategy, new pyridyl-indole hybrids 4a-y and indole intermediates 3a-e were synthesized using multicomponent one pot reaction. The synthesized compounds were subjected to screening for antimalarial activity against chloroquine sensitive (D6) and chloroquine resistant (W2) strains of Plasmodium falciparum. Several compounds exhibited antimalarial activity with IC50 values in the range of 1.47-9.23 mu M, and 1.16-7.66 mu M, for D6 and W2 strains, respectively. Compounds 4a, 4k and 4u showed the highest selectivity index among all the tested compounds (S.I. ranged 3.8-10). Binding interactions between the active antimalarial compounds and the active site of quadruple mutant Plasmodium falciparum dihydrofolate reductase enzyme have been investigated using molecular docking analysis.

GC-MS and GC-IR analysis of regioisomeric cannabinoids related to 1-(5-fluoropentyl)-3-(1-naphthoyl)-indole

The compounds in this study are the regioisomeric 2-, 3-, 4-, 5-, 6- and 7-(1-naphthoyl) substituted 1-(5-fluoropentyl)-indoles and the 3-(1-naphthoyl) substituted isomer in this series is also known as AM-2201. These compounds are structurally similar to JWH-018 except for the additional fluorine at the terminal end of the n-pentyl side-chain. These six regioisomeric compounds have the identical elemental composition (C24H22FNO) and differ in the position of attachment of the 1-napthoyl group on the indole ring. The electron ionization mass spectra showed similar major fragment ions with a molecular radical cation of significant abundance at m/z 359. The six compounds have similar fragment ions at m/z 127 and 155 for the naphthyl and naphthoyl cations. There is a prominent fragment ion at m/z 342 [M-17](+) in the EI-MS of 1-(5-fluoropentyl)-3-, 4-, 5- and 6-(1-naphthoyl)-indoles due to the loss of the hydroxyl group and this ion is most prominent in the 3-(1-naphthoyl) substituted isomer (AM-2201). The six compounds were separated using gas chromatography on a capillary column containing a trifluoropropylmethyl polysiloxane (Rtx-200) stationary phase. The elution order appears to be related to the steric crowding of the indole ring substituents. The 7- and 2-(1-naphthoyl) substituted isomers eluted first due to the possibility for maximum interactions between the naphthyol and alkyl side-chains. The vapor phase infrared spectra differentiate among these six compounds based on the position of the 1-naphthoyl group on the indole ring. The vapor phase spectra for these compounds are compared to the non-fluorinated analogues, JWH-018 and its regioisomeric equivalents. (C) 2018 Published by Elsevier B.V.
