Synthesis, antimicrobial, antimycobacterial and structure–activity relationship of substituted pyrazolo-, isoxazolo-, pyrimido- and mercaptopyrimidocyclohepta[b]indoles
摘要:
A new class of heterocycles, specifically substituted pyrazolo-, isoxazolo- and pyrimidocyclohepta[b]indoles, has been prepared by condensation of substituted 7-(hydroxymethylene)-7,8,9,10-tetrahydrocyclohepta[b]indol-6(5H)-ones with hydrazine hydrate, hydroxylamine hydrochloride, phenylhydrazine, urea and thiourea, respectively. The structures of the compounds were established by IR, H-1 NMR, C-13 NMR, mass spectral analysis, X-ray diffraction, and the compounds have been screened for in vitro antimicrobial and antimycobacterial against Mycobacterium tuberculosis H37Rv (MTB). Among the compounds screened, five substances were found to have an MIC of 3.12 mu g/ml or greater against MTB. Structure-activity relationship (SAR) analyses and in silico drug relevant properties (HBD, HBA, PSA, c Log P, M.wt) confirmed that the compounds are potential lead compounds for future drug discovery studies.

title ring systems have been developed from 1H-indole-2-butanoic acid, which was easily prepared from 2-fluoro-1-nitrobenzene in four steps. Heating 1H-indole-2-butanoic acid in toluene containing p-toluenesulfonic acid at 110°C furnished 1,2,3,9-tetrahydro-4H-carbazol-4-one in 88% yield. Heating this same acid in toluene with no added acid gave 8,9-dihydropyrido[1,2-a]indol-6(7H)-one in 90% yield. The

Synthesis and Oxidative Cleavage of Oxazinocarbazoles: Atropselective Access to Medium-Sized Rings
m-chloroperoxybenzoic acid (MCPBA) is used to cleave the indole 2,3-double bond that this system contains. This results in a competition between two processes, oxidative cleavage of the double bond and a pinacol-typerearrangement, both of which occur with very high diastereoselectivity. The balance between the two processes is studied as a function of the substrate structure. Extensive use of X-ray crystallographic
