Synthesis, Characterization and Antibacterial Activity Studies of Some N-Acyl-N'-aryl Thiourea Derivatives
Some N¬-acyl-N'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. The structures of synthesized compounds have been characterized by IR, 1HNMR spectral studies. The synthesized compounds 5(a-f) have been screened for antibacterial activity. The effect of the structure of the investigated compounds on the antibacterial activ...
متن کاملA mild and facile one-pot synthesis of N-methyl-acyl-pyrroles.
N-Methyl-3-acylpyrroles were synthesized via a multicomponent reaction of dimethylacetylene dicarboxylate (DMAD), N-methylhydroxylamine and acylchlorides in the presence of KHCO(3). For comparison both conventional and microwave protocols were examined in this procedure. The reaction is clean and gives the products in good to excellent yields under conventional heating conditions at 40 degrees ...
متن کاملPhosphine-catalyzed intramolecular γ-umpolung addition of α-aminoalkylallenic esters: facile synthesis of 3-carbethoxy-2-alkyl-3-pyrrolines.
An array of N-tosylated α-aminoalkylallenic esters was prepared and their cyclization under the influence of nucleophilic phosphine catalysts was explored. The α-aminoalkylallenic esters were prepared through aza-Baylis-Hillman reactions or novel DABCO-mediated decarboxylative rearrangements of allenylic carbamates. Conversion of these substrates to 3-carbethoxy-2-alkyl-3-pyrrolines was facilit...
متن کاملMicrowave-Assisted Heck Arylations of Non-Activated N-Acyl-3-pyrrolines with Arenediazonium Tetrafluoroborates
The carbon-carbon bond forming process is one of the most important transformations in organic synthesis aimed at the construction of complex molecules. In this regard, the Heck reaction poses as a pivotal synthetic methodology widely used for the formation of carbon-carbon bonds starting from olefins and an electrophile. An alternative of growing importance to the conventional Heck reaction wa...
متن کاملFacile construction of highly functionalized 2-pyrrolines via FeCl(3)-catalyzed reaction of aziridines with arylalkynes.
A series of highly functionalized 2-pyrrolines have been constructed by using a novel FeCl(3)-catalyzed reaction of aziridines with arylalkynes, in which an aryl-substituted alkenyl cation is involved.
