Herein, we report a palladium-catalyzed dehydro-genative cross-coupling of indoles with cyclic enones to give beta-indolyl cyclic enones under mild and neutral reaction conditions. The key to the success is to explore a mild condition, which ensures the indole C-H activation and subsequent syn beta-hydride elimination through rapid enolization isomerization of Pd(II)-enolate while suppressing other undesired side reactions. Synthetic utility has also been demonstrated in the flexible transformation of the coupling products to meta-phenols and benzo [a] carbazoles.

Extended knowledge of 3,4-Dibromothiophene

The compounds in this study are the six regioisomeric 2-, 3-, 4-, 5-, 6- and 7-formyl indoles and the corresponding six regioisomeric N-n-pentylindole aldehydes. These compounds can serve as precursor chemicals and synthetic intermediates for a number of synthetic cannabinoid drugs. These two sets (the six regioisomeric indole aldehydes as well as the six regioisomeric pentylindole aldehydes) each have identical elemental compositions and differ in the position of attachment of the aldehyde group on the indole ring. The electron ionization mass spectra for the indole aldehydes were essentially identical. However, the vapor phase infrared spectra showed differences in the absorption frequencies for the N-H and carbonyl groups based on intramolecular interactions. The associated N-H absorption band occurs as low as 3467 cm(-1) while the free band is as high as 3517 cm(-1). The aldehyde carbonyl band for the indole aldehydes varies from 1713 cm(-1) to 1686 cm(-1). Substitution of the aldehyde group on the pyrrole ring for the N-n-pentylindole aldehydes yields lower carbonyl absorption bands. The EI mass spectra for the pentylindole aldehydes are identical with little information for differentiation among these six regioisomeric compounds. The six compounds were separated on a capillary column using gas chromatography and the elution order appears to be related to the steric crowding of the indole ring substituents.

The reaction of 4,5-dihydro-3H-1,2,4-triazino[5,6-b]indole-3-thion with propargyl bromide, in EtOH at 80 degrees C, produces mono-propargylated 3-(prop-2-one-1-ylthio)-5H-1,2,4-triazino[5,6-b]indole. Further reaction of this compound with propargyl bromide, in DMF in the presence of K2CO3 at room temperature, produced successfully double-propargylated 5-(prop-2-one-1-yl)-3-(prop-2-one-1-ylthio)-5H-1,2,4-triazino[5,6-b]indole. The Cu(I)-catalyzed click reaction of these propargylated compounds with different aromatic azides at room temperature, afforded new derivatives of 1,2,3-triazoles-linked 1,2,4-triazino[5,6-b]indole with high yields. The in vitro antibacterial activities of the novel 1,2,3-triazoles were screened. The binding modes of these compounds to three enzyme active sites were determined by a molecular docking study. Docking studies demonstrated the most potent compounds; and binding maps revealed that the activities might be attributed to the hydrophobic interactions, hydrogen bonds, cation-pi and pi-pi contacts with the active sites.

The development of a rational strategy to achieve the complete regioselectivity and the capability to switch regioselectivity is an appealing, yet challenging, puzzle in transition-metal-catalyzed oxidative Ar-H/Ar-H cross-coupling. Disclosed herein is an iridium-catalyzed C2/C4 regioselective C-H heteroarylation of indoles with the help of a pivaloyl group at the C3 position. The judicious choice of the catalytic systems allows the C2-heteroarylation of indole via a concerted metalation-deprotonation (CMD) process and the C4-heteroarylation via a trimolecular electrophilic substitution (S(E)3) pathway. The oxidants Cu(OAc)(2)H2O and Ag2O are demonstrated to play a vital role in the C2/C4 regioselectivity. In this Article, a heteroaryl-Ir(III)-heteroaryl complex prior to reductive elimination is successfully isolated and characterized, which represents the first example of capturing the bis(hetero)aryl metallic intermediate in oxidative Ar-H/Ar-H cross-coupling. The regiodivergent heteroarylation of indoles developed herein provides an opportunity to rapidly assemble diverse C4- and C2-heteroarylated indoles.
