The structural elucidation of these compounds is based on IR, ¹H NMR, ¹³C NMR, mass spectral data and elemental analysis. These compounds have been tested for their antibacterial activity against Escherchia coli, Enterobacter aerogenes, Staphylococcus aureus and Salmonella typhi by cup-plate method. <br/> <br/>Page(s): 97-102 http://nopr.niscair.res.in/handle/123456789/2941 Title: Synthesis and in vitro study of biological activity of heterocyclic N-Mannich bases <br/> <br/>Authors: Shah, T B; Gupte, A; Patel, M R; Chaudhari, V S; Patel, H; Patel, V C <br/> <br/>Abstract: Three series of N-Mannich bases of 3,4-dihydropyrimidine-2(1H)-ones(DHPMs) 7a-g, 8a-g, and 9a-g have been prepared by Mannich reaction of DHPMs 4a-c with seven different heterocyclic secondary amino compounds 6a-g and formaldehyde 5. The precursors DHPMs 4a-c have been derived by a Biginelli reaction of three aromatic aldehydes 1a-c with ethylacetoacetate 2 and urea 3. The chemical structure of all the three series of N-Mannich bases have been elucidated by elemental analysis and spectral studies (IR, ¹H and ¹³C NMR). They have been assayed in vitro for their biological activity against E. coli and B. subtilis bacterial species and A. niger and C. albicans fungal microorganisms. <br/> <br/>Page(s): 88-96 http://nopr.niscair.res.in/handle/123456789/2940 Title: Synthesis of functionalized diaryl alkanes from azines <br/> <br/>Authors: Manih, Rudolf M; Myrboh, Bekington <br/> <br/>Abstract: Substituted diaryl alkanes are synthesized from benzalazines and acetophenone/propiophenone azines via Friedel Craft`s reaction with substituted mono- and poly-nuclear aromatic hydrocarbons. Diaryl methanes/ethanes and propanes are obtained by reaction with benzalazine, N,N'-bis (1-phenyl) azine and N, N’-bis (1-propyl) azine, respectively. <br/> <br/>Page(s): 146-151
