G-QSAR of Novel 2-{[2-(1H-imidazol-1-yl)ethyl]sulfanyl}-1H- benzimidazole Derivatives
In the present work, we have applied group quantitative structure–activity relationships (G-QSAR) for exploring the relationship between the structures of a new emerging family of 2-{[2-(1Himidazol-1-yl)ethyl]sulfanyl}-1H-benzimidazole derivatives and their antiprotozoal activities. We have developed descriptive models, in order to aid in further optimization and development of newer antiprotoz...
متن کاملStudies on the Alkylation of Quinolin-2(1h)-one Derivatives
Alkylation of quinolin-2(1H)-one (1) and its C(6) and C(7) substituted dervatives (OMe, OBn, and Cl) with 2-bromoacetophenone or chloroacetone under basic condition (K2CO3 in DMF) gave a mixture of N1and O2alkylated products with the former one as a major product. However, alkylation of 8-methoxy-, 8-benzyloxy-, and 8-chloroquinolin-2(1H)-ones under the same reaction conditions gave exclusively...
متن کاملApplication of N-methylimidazole for the Synthesis of Dimethyl-{3-methyl-2-[(alkoxycarbonyl) anilino]-2,3-dihydro-1H-imidazol-1-yl)}-2-butenedioate Derivatives
A one-pot synthesis ofdimethyl-{3-methyl-2-[(alkoxycarbonyl) anilino]-2,3-dihydro-1Himidazol-1-yl)}-2-butenedioatesanddimethyl-2-[(alkoxycarbonyl)anilino]-2-butenedioates derivatives via reactions between dimethyl acetylenedicarboxylate,1-methylimidazoleand N-phenylcarbamates is described. The mild reaction condition, simple mixing of the starting materials and good yields exhibit the synthetic...
متن کاملCrystal structures of the two salts 2-methyl-1H-imidazol-3-ium nitrate–2-methyl-1H-imidazole (1/1) and 2-methyl-1H-imidazol-3-ium nitrate
The title salts, C4H7N2 (+)·NO3 (-)·C4H6N2, (I), and C4H7N2 (+)·NO3 (-), (II), were obtained from solutions containing 2-methyl-imidazole and nitric acid in different concentrations. In the crystal structure of salt (I), one of the -NH H atoms of the imidazole ring shows half-occupancy, hence only every second mol-ecule is in its cationic form. The nitrate anion in this structure lies on a twof...
متن کامل3-Methyl-1-propargylquinoxalin-2(1H)-one
The ten-membered fused ring of the title compound, C(12)H(10)N(2)O, is essentially planar in the two independent mol-ecules of the asymmetric unit (r.m.s. deviations = 0.012 and 0.015 Å).
