Novel quinazoline ring synthesis by cycloaddition of N-arylketenimines with N,N-disubstituted cyanamides.
The reaction of N-aryl-substituted ketenimines with N,N-disubstituted cyanamides or (MeS)2C=N-CN under high pressure afforded 4-(N,N-disubstituted amino) or 4-(MeS)2C=N-substituted quinazoline derivatives, respectively. These products were formed by [4+2] cycloaddition between the aza-diene moieties of the N-arylsubstituted ketenimines and cyano groups. A 4-(unsubstituted amino)quinazoline deri...
متن کاملSynthesis and Crystal Structures of N,N0-Disubstituted Piperazines
The structure of 1,4-diphenylpiperazine (1) was determined; it crystallized in the orthorhombic space group Pbca, a = 8.6980(7), b = 8.4287(7), c = 17.6359(15), V = 1292.94(19), Z = 4. Three novel N,N0-disubstituted piperazines were synthesized via reductive amination of piperazine or N-diphenylmethylpiperazine. The products were characterized by NMR and X-ray crystallography. 1,4Diphenethylpip...
متن کاملOne-pot synthesis of diverse N,N'-disubstituted guanidines from N-chlorophthalimide, isocyanides and amines via N-phthaloyl-guanidines.
A sequential one-pot approach towards N,N'-disubstituted guanidines from N-chlorophthalimide, isocyanides and amines is reported. This strategy provides straightforward and efficient access to diverse guanidines in yields up to 81% through previously unprecedented N-phthaloylguanidines. This protocol also features wide substrate scope and mild conditions.
متن کاملSynthesis and Pharmacology of Some New N,N- Disubstituted Dithiocarbamate Derivatives
In this study, twenty two new N,N-disubstituted dithiocarbamate derivatives were synthesized. The structures of the compounds were confirmed by IR, 1H-NMR, mass spectroscopy and elemental analysis. Anticholinergic activities of the compounds were evaluated by the tests performed on isolated rat ileum and were compared with atropine sulfate. 1-(Diphenylamino)-1-oxopropan-2-yl 4-methylpiperazine ...
متن کاملSynthesis and antimycobacterial activity of some N,N′-disubstituted isonicotinohydrazide derivatives
A new series of antimycobacterial agents 2a–j, 3a–d, 6b–f,j, and 7b,f was designed, synthesized and evaluated for antimycobacterial activity against different mycobacterium species i.e. M. tuberculosis, M. avium, and M. intracellulare in an agar dilution method. Some of these compounds (2e, 3a–d) were highly potent with in vitro activity against M. tuberculosis H37Rv and clinical isolates (sens...
