Ease of handling, regioselectivity, metal-catalyst free, and good yields are the advantageous of this protocol. The structures were corroborated spectroscopically (IR, 1H- and 13C-NMR, and EI-MS) and by elemental analysis. In this one-pot reaction one new C-S and two C-C bonds are formed.

This protocol provides an alternative method for application in combinatorial and parallel synthesis in drug discovery. The value of this method lies in its simplicity, regioselectivity, and good yields. The structures of new synthesized compounds were corroborated spectroscopically (IR, 1H- and 13C-NMR, and EI-MS). A plausible mechanism for this type of reaction is proposed (Scheme 2).

This involves reaction of isatin, 1-phenyl-2-(1,1,1-triphenyl-l 5-phosphanylidene)-1-ethanone, and benzylamine derivatives or aliphatic amines in the presence of alkyl acetoacetate (1,3-dicarbonyl compounds) in dry methanol under reflux conditions. The reactive 1:1 enaminone, which is obtained from the addition of the amine to 1,3-dicarbonyl compound, adds to the a,b-unsaturated ketone, which is formed from the reaction of isatin and 1-phenyl-2-(1,1,1-triphenyl-l 5-phosphanylidene)-1-ethanone, to produce the alkyl 1 0-benzyl-2 0-methyl-2-oxo-6 0-phenyl-1 0 H-spiro[indoline-3,4 0-pyridine]-3 0-carboxylate derivatives in excellent yields.

Intermediate dihydroquinoxalines, derived from the addition of o-phenylenediamine to dialkyl acetylenedicarboxylates, possess enamine character, and react with arylsulfonyl isocyanates to produce the title compounds.

For example, Fezatione is an antifungal and antitrichophytic [1]. In addition, these compounds display a central role in modern synthetic organic chemistry [2]. Metal enolates of N-acyl-1,3-oxazolidine-2-tiones have been used as chiral auxiliaries for aldol type reactions with high diastereoselectivity [3]. As part of our work devoted to the synthesis of important heterocycles especially heterocyles with two heteroatoms [4] herein we report a novel, one-pot, three-component reaction for the synthesis of 1,3-thiazolidine-2-thiones.

The dialkyl 2-[(Z)phenylhydrazono]succinate intermediate, which is prepared in situ from the mixture of phenylhydrazine and dialkyl acetylenedicarboxylate reacts with aroyl chloride or fumaryl chloride to afford the title compounds. Different types of compounds containing COCl functional group were used to investigate the scope and limitation of the reaction. Two eCO 2 R and eO 2 C groups at 3-and 5-position are potentially capable to convert to other functional groups. The reaction conditions are relatively mild and the yields are good.

This involves the reaction of arylsulfonyl isocyanates and diketene in the presence of N-heteroaromatic compounds such as 1,3,5-triazine, 1-methyl-1H-imidazole, or pyridine as catalyst. The reactive 1:1 zwitterions obtained from the addition of N-heteroaromatic compound to arylsulfonyl isocyanates were trapped by diketene to produce functionalized sulfonamide and 1,3-oxazine-2,4(3H)-dione derivatives.
