Five new acyl derivatives of isonicotinic acid hydrazide such as N-(2,4-dichlorophenoxyacetyl)-isoniotinic acid hydrazide (I), N-(p-nitrobenzoyl)-isonicotinic acid hydrazide (II), N-benzoylisonicotinic acid hydrazide (III), N-furoylisonicotinic acid hydrazide (IV) and N-(p-aminobenzoyl)-isonicotinic acid hydrazide (V) were synthesized. They were obtained by the action of 2,4-dichlorophenylacetyl chloride, p-nitrobenzoyl chloride, benzoyl chloride, furoyl chloride and p-aminobenzoyl chloride with isonicotinic acid hydrazide in pyridine solution. Evaluated for their in vitro antitubercular activity against Mycobaterium tuberculosis H$_{37}$ R$_{\upsilon}$ N-furoylisonicotinic acid hydrazide (IV) showed antitubercular activity at 1${\gamma}$/ml.

In order to synthesize N,N-di-(polyoxyethylene) perfluoroacyl amines and the surface active monoperfluoroacyl aza crown ethers, it is performed as follow. Six of N,N-di(polyoxyethylene) perfluoro acyl amines were synthesized from perfluoroalkanoic acids with ethanol followed by oxyethylation with triethylene glycol mono chloride or tetra ethylene glycol mono chloride and six of N-perfluor acyl monoaza crown ethers by cyclization of corresponding N,N-di(polyoxy ethylene} perfluoro acyl amines with p-toluene suflonic chloride-NaOH/dioxane, p-toluene sulfonyl chloride KOH/dioxane and benzene sulfonic chloride-KOH/dioxane systems.

The reaction of 6-chloro-2-hydrazinoquinoxaline 4.oxide(10) with acetylacetone or dibenzoylmethane gave 6-chloro-2-(3,5-disubstituted pyrazol-1-yl)quinoxaline 4-oxides (11) through the intramolecular·cyclization.The chlorination of compound 11 with phosphoryl chloride afforded 3,6-dichloro-2-(3,5-disubstituted pyrazol-1-yl)quinoxalines (12), whose reaction with hydrazine hydrate provided 6-chloro-3-hydrazinodehydes, benzenesulfonyl chloride, substituted benzoyl chlohdes or acyl chlorides gave novel pyrazolylquinoxalines (14-17).

Two different acyl substituents were introduced at the lower rim of calix[4]arene by the two step reactions. Calix[4]arenes (1) reacted with 3,5-dinitrobenzoyl chloride to yield monosubstituted calix[4]arene (2). Second substitution was achieved by the reaction of 2 with various acyl chlorides. Aminomethylation of monobenzoylated calix[4]arene was conducted successfully in the presence of secondary amine and formaldehyde.

Choline esters that are used with substrate of BChE-catalyzed hydrolyses were synthesized by two methods. First, 2-chloroethyl thiohexanoate, 2-chloroethyl thioheptanoate, and 2-chloroethyl thiooctanoate were synthesized by the treatment of hexanoyl chloride with ethylene sulfide. Hexanoyl thiocholine and octanoyl thiocholine were synthesized by using 2-chloroethyl thiohexanoate and 2-chloroethyl thiooctanoate with trimethyl amine. Second, after reaction of ethylene sulfide and dimethyl amine, followed by acylation with acid anhydride and then heptanonyl thiocholine, decanoyl thiocholine were synthesized by treatment of methyl iodide.

Three di-acyl chlolide reagents, adipoyl chloride, terephthaloyl chloride and isophthaloyl chloride, were used as spacer reagents to prepare bonded type of three cellulose (3,5-dimethylphenyl)carbamate (CDMPC) chiral stationary phases (CSPs). The CDMPC CSPs were prepared using these three acid chlorides as spacer agents at the 6-position of the primary hydroxyl group on the glucose unit of cellulose regioselectively. The chiral recognition ability of the prepared CSPs for five racemates was evaluated by normal-phase high-performance liquid chromatography (HPLC) with the following mobile phases: hexane/isopropanol (IPA), hexane/IPA/tetrahydrofuran (THF) and hexane/IPA/chloroform. The result showed that these prepared CSPs can be used in THF and chloroform solutions and the chiral recognition abilities of the CSPs were improved depending on the eluents and chiral samples.

The synthesis of N-acrylylpyrrolidone has been carried out by the reaction of pyrrolidone and acrylyl chloride. The study on the copolymer of N-acrylylpyrrolidone and styrene is attempted.The copolymerization of N-acrylylpyrrolidone and styrene is carried out in benzene.Monomer reactivity ratio of N-acrylylpyrrolidone and styrene was calculated by Fineman and Ross equation. It is observed that the copolymer of N-acrylylpyrrolidone and styrene has random distributed acyl-lactam function on the vinyl polymer backbone.
