  • The synthesis and antimicrobial activity of N-substituted glycol derivatives of Norfloxacin were described. Norfloxacin was treated with chloroacetyl chloride to yield chloroacetyl norfloxacin (1). This compounds was reacted with alkyldiamines to afford bivalent ligand quinolone carboxylic acids (2-6), which was added to pivaloyloxymethyl chloride to give bivalent ligand pivaloyloxymethyl quinolone carboxylates (7-11). Chloroacetyl norfloxacin (1) treated with alkylamines to obtain monovalent ligand quinolone carboxylic acids (12-15), which was reacted with pivaloyloxymethyl chloride to get monovalent ligand pivaloyloxymethyl quinolone carboxylates (16-19). Free carboxylic quinolones (2-6, 12-15) showed little stronger activities to their pivaloyloxymethyl esters (7-11, 16-19). In monovalent ligand quinolone analogues, longer a1kyl chain com-pounds showed stronger activities than shorter one.

  • Thebaine was reacted with diisopropyl azodicarboxylate to give northebaine. Diels-Alder reaction between the compound and nitrosobenzene was attempted. The hydrogen of the adducted northebaine was substituted with chloroacetyl chloride and succinic anhydride. We have synthesized the new thebaine derivatives with phenylhydroxylamine at 14-carbon and also acetyl or succinyl at 17-nitrogen with yields of 22% and 16%.

  • A facile and effective method has been developed for the synthesis of a novel series of benzofuran derivatives via N-acylation, O-alkylation and intramolecular condensation reactions, starting from readily available substituted o-hydroxy aryl ketone, and chloroacetyl arylamides. This metal-free transition process is characterized by mild reaction conditions, atom economy, short reaction time and a high yield with a decreased amount of by-products.

  • Some chloroacetamide derivatives were synthesized from 2,6-dialkyl, aniline 4-chloroaniline, or 3,4-dichloroaniline with alkyl 2-bromopropionate and chloroacetyl chloride and identified by elemental analyses, NMR, and GC/MS spectra as N-(1'-methoxycarbonylethyl)-N-chloroacetyl-2,6-dimethylaniline(ACRI-S-8609), etc. These compounds synthesized were subjected to the test for pre-emergence herbicidal effecs on some grass weeds(Digitaria adscendens, Setaria viridis, Echinochloa crus-galli) and broad leaf weeds(Portulaca oleracea, Amaranthus lividus, Chenopodium album) in pots applied as wettable powder formulations. It was found that N-(1'-ethoxycarbonylethyl)-N-chloroacetyl-2,6-dimethylaniline(ACRI-S-8701) has the highest herbicidal effect on grass weeds, which corresponds to a 95% control effect at an application of 200g a.i/10a. Whereas, some chloroacetamide derivatives derived from 4-chloroaniline or 3,4-dichloroaniline had very weak herbicidal effects on grass and broad leaf weeds.

  • Reaction of oxazolin-5-ones 1 with p-amino-diphenylamine was resulted in the formation of the corresponding imidazoline-5-ones 2 which on treatment with sulphur afforded phenothizaines 3. Acridine derivatives 5 were obtained from acetylaminodiphenyl amines derivatives 6 on heating with AnCl$_2$ at $200^{\circ}C.$3 reacted with chloroacetyl chloride to give 7 which reacted in turn with different amines to give 8. Antibacterial activity of the obtained products was studied.

  • A new class of Chalcone-Sulphonamide hybrids has been designed by condensing appropriate sulphonamide scaffold with substituted chalcones tethered by chloroacetyl chloride as a multi-target drug for therapeutic treatment. Chalcones were prepared by Claisen-Schmidt condensation of a substituted aldehyde with para aminoacetophenone. These Chalcone-Sulphonamide hybrids were screened by means of their antibacterial activity by NCCLS method. Among all these compounds, 5e and 5c displayed more potent growth inhibitory activity against Staphylococcus epidermidis and Pseudomonas aeruginosa bacteria respectively. Further, these hybrids were evaluated for their antifungal activity, among all hybrid 5a exhibited potent antifungal activity. The synthesized compounds were characterized by FT-IR, $^1HNMR$, $^{13}CNMR$ and HR-LCMS and spectral study supports the structures of synthesized Chalcone-Sulphonamide hybrids.

  • Chloroacylation of 3-amino-2-phenylpyrazole-4-carboxamide (2) using chloroacetyl-(propionyl) chloride affording 6-chloromethyl(ethyl)-1-phenylpyrazolo[3,4-d]pyrimidin-4[5H]-one (3) or (6). Chlorine atom in compound (3) or (6) underwent nucleophilic substitution reaction with primary or secondary amines to give 6-alkyl(aryl)aminomethyl(ethyl)-1-phenylpyrazolo[3,4-d]pyrimidin-4[5H]-one (4a-g,7a-f). When arylaminomethyl( ethyl)pyrazolopyrimidine was treated with formaline (30%) solution in ethanol, underwent Mannich reaction to afford imidazopyrazolopyrimidines (5a-e) and pyrazolopyrimidopyrimidines (8a-e). Chloromethylpyrimidine derivative 3 was converted into the corresponding mercaptomethylpyrazolopyrimidene 9, Which cyclized using bromomalononitrile or phenacyl bromide into pyrazolopyrimidothiazine 11,12.
