A new Pd(II)-catalyzed cascade sequence for the formation of polyheterocycles, from simple starting materials, is reported. The sequence is applicable to both indole and pyrrole substrates, and a range of substituents are tolerated. The reaction is thought to proceed by a Pd(II)-catalyzed C-H activated Heck reaction followed by a second Pd(II)-catalyzed aza-Wacker reaction with two Cu(II)-mediated Pd(0) turnovers per sequence. The sequence can be considered a formal [4 + 2] heterocyclization.

Paragraph 0021-0032, (2018/09/08)
The invention relates to a method of synthesizing a 4,5-disubstituted 1,2,3-triazole compound. The method comprises the following step of by taking pyridine, halohydrocarbon, sulfonic ester, aldehydeand sodium azide as raw materials, and performing room-temperature reaction with a one-pot method. The synthetic method does not need a metal-containing catalyst, has the advantages of high yield of synthetic products, mild reaction condition, good functional group compatibility and the like, is simple in operation step, mild in reaction condition and wide in application range of a substrate, hasinnovativeness and a potential practical value and is suitable for industrial production.

supporting information, p. 4884 - 4887 (2015/04/27)
A solvent-controlled switchable C-H alkenylation of 4-aryl-1H-pyrrole-3-carboxylates via a Pd(OAc)2 catalyzed oxidative Heck reaction was first realized. The corresponding C2 and C5 alkenylation products were obtained in good yields with high regioselectivities, respectively. The selective C5-alkenylation was successfully applied to the total synthesis of (±)-rhazinilam.

Page/Page column 31, (2008/06/13)
The present invention provides compounds of formula I and pharmaceutically acceptable salts thereof. The formula I compounds inhibit the tyrosine kinase activity of growth factor receptors such as VEGFR-2, FGFR-1, PDGFR, HER-1, HER-2, thereby making them useful as anti-cancer agents. The formula I compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.

Pyrrole analogues of the NNRTI S-1153 were synthesized and tested as anti-HIV-1 agents. Among test compounds 5-(3,5-dichlorophenylthio)-4-isopropyl-1-(4-pyridylmethyl)-1H-pyrrole-3- methanol was the most active in cell-based assays against HIV-1 wt and K1
Flash vacuum pyrolysis of N-alkenylbenzotriazoles and N-alkenylisoxazolones

, p. 665 - 671 (2007/10/03)
The flash vacuum pyrolysis of 1-(2-ethoxycarbonylethenyl)benzotriazole has been reinvestigated, and the processes leading to the formation of ethyl indole-3-carboxylate and 2-ethoxyquinolin-4(1H)-one elucidated. Similar pathways are followed in the flash vacuum pyrolysis of the corresponding benzisoxazolone. Some N-ethenylisoxazolones have been pyrolysed to form pyrroles, but rearrangement of the intermediate carbenes may be observed. Photolysis of the isoxazolones gives carbenes that may be captured by solvent or give pyrroles. CSIRO 2000.
