DFT studies of conversion of methyl chloride and three substituted chloromethyl tetrahydrofuran derivatives during reaction with trimethylamine
B3LYP/6-31+G level computations were performed for the formation of four trimethylammonium salts in the reaction of methyl chloride (1a), (S)-1,4-andydro-5-chloro-2,3,5-trideoxypentitol (2a), (2S,5S)-2,5-andydro-6-chloro-1,3,4,6-tetradeoxyhexitol (3a) and methyl 5-chloro-2,3,5-trideoxy-β-D-pentofuranoside (4a) with trimethylamine. All the structures were fully optimized in the gas phase, in chl...
متن کاملStudies on inclusion complexes of 2-[Substituted arylideamino]-1, 3, 4-thiadiazino [6,5b]indole with β- Cyclodextrin
Inclusion complexes of 2-[Arylidenamino]-1,3,4-thiadiazino[6,5b]indoles have been prepared with β-cyclodextrin so as to increase the solubility of these compounds in polar medium which may increase theirbioaccessibility. The formation of inclusion complexes is known from the study of changes in physical andspectral properties of the compounds. The stability of the inclusion complexes has been s...
متن کاملREACTION OF 4-METHYL- 1 2,4-TRIAZOLINE- 3,5-DIONE WITH DI AND TRI-SUBSTITUTED STYRENES S.E. Mallakpour* and G.B. Butler**
2,4,6-Triisopropylstryrene was synthesized in a single step via the Witting Reaction from the corresponding aldehyde. The reaction of three styrene's derivatives, 2,6-dimethylstyrene, 2,4,6-trimethylstyrene, and 2,4,6- triisopropylstyrene with 4-methyl-l,2,4-triazoline-3,5-dion(M eTD) was investigated. These reactions are instantaneous at room temperature and lead to the formation of 2: 1 ...
متن کاملSynthesis and Biological Evaluation of 4-hydroxychromenyl arylmethyl-6-hydroxy pyrimidine-2, 4-dione Derivatives
Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed ...
متن کاملMicrobiological Evaluation of 4-substituted-imidazolidine Derivatives
In the present studies, two series of 4-substituted-imidazolidines (IIIa-i and IIIj,k) were synthesized by reacting different tetrahydro-di-Schiff bases (IIa-i and IIj,k) with p-diethylaminobenzaldehyde/ dimethylaminobenzaldehyde. The title compounds were evaluated for their antibacterial and antifungal actions against some selected microbes. The results of microbiological evaluation revealed t...
