A safe and convenient method is described for the synthesis of the title compounds starting from glycine and an azomethine. The amino group of glycine is protected by reaction with ethyl acetoacetate and the carboxyl group is activated through the formation of a mixed anhydride. Condensation between these glycine derivatives and imino compounds in the presence of triethylamine leads to stereospecific synthesis of 3-(α-methyl-β-carbonyl-vinylamino)-2-azetidinones in about 50% yield. The vinylamino...

A safe and convenient method is described for the synthesis of the title compounds starting from glycine and an azomethine. The amino group of glycine is protected by reaction with ethyl acetoacetate and the carboxyl group is activated through the formation of a mixed anhydride. Condensation between these glycine derivatives and imino compounds in the presence of triethylamine leads to stereospecific synthesis of 3-(α-methyl-β-carbonyl-vinylamino)-2-azetidinones in about 50% yield. The vinylamino side chain can be hydrolyzed under mild condition to form 3-amino-2-azetidinones which are acylated to form α-amido-β-lactams. Sixteen title compounds have been synthesized and five of them show inhibitory activity against β-lactamase.

The described automatic generation of virtual bio - active compounds starts from pharmacophore and pre - selected fragments. The generation process consists of three stages: selection of fragments, assemblage of fragments and conformation flexible searching. This method is demonstrated by an example that sixteen virtual bio - active compounds were generated starting from HIV - 1 protease inhibitors pharmacophore in this work. The results of conformation analysis showed that the pharmacophore is contained in the favorite conformers of the generated structure. It was showed that this method could generate virtual bio - active structure effectively. In comparing of the results from 3D structure searching, the generated structures have novel structural features and they are easier to be synthesized.
