C-2-Symmetric Dinickel Catalysts for Enantioselective [4+1]-Cycloadditions

Dinickel naphthyridine-bis(oxazoline) catalysts promote enantioselective intermolecular [4 + 1]-cycloadditions of vinylidene equivalents and 1,3-dienes. The products of this reaction are methylenecyclopentenes, and the exocyclic alkene is generally obtained with high Z selectivity. E- and Z-dienes react in a stereoconvergent fashion, providing cycloadducts with the same sense of absolute stereochemistry and nearly identical ee values. This feature allows dienes that are commercially available as E/Z mixtures to be used as substrates for the cycloaddition. A DFT model for the origin of asymmetric induction is provided.

Synthesis of thieno[2,3-b]benzo[1,8]naphthyridine-2-carboxylic acids under microwave irradiation and interaction with DNA studies

The microwave-enhanced synthesis of 2-chloro-3-formylbenzo[1,8]naphthyridines 3a-c has been achieved rapidly in good yield via the Vilsmeier-Haack cyclisation of N-(4-methylquinolin-2yl) acetamide 2a-d. The precursors N-(4-methylquinolin-2-yl) acetamide derivatives were effectively prepared in a single step from 2-aminoquinoline and acetic anhydride in presence of Amberlite-120A cation exchange catalyst under microwave irradiation. Condensation of 3a-d, with thioglycolic acid under microwave irradiation using anhydrous potassium carbonate as catalyst afforded thieno[2,3-b]benzo[1,8]naphthyridine-2-carboxylic acids (TBNCS) 4a-g. Elemental analysis, IR, H-1 NMR, and mass spectral studies were used to characterize these compounds. The interaction of thieno[2,3-b] benzo[1,8]naphthyridine-2-carboxylic acid (TBNC)(4a) with CT-DNA was studied by UV-Vis, viscosity as well as thermal denaturation methods. On binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. Binding parameters, determined from spectrophotometeric measurements indicated a binding constant of 1.8 X 10(6) M-1. The thieno[2,3-b]benzo[1,8] naphthyridine-2-carboxylic acid (4a) increases the viscosity of sonicated rod- like DNA fragments. The binding of TBNC to DNA increased the melting temperature by about 4 degrees C. DNA interaction studies suggest that (4a) binds to calf thymus DNA (CT-DNA).

Chemical behavior of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]chromene-6-carboxaldehyde towards carbon nucleophilic reagents

The chemical behavior of 6-formylkhellin (1) was investigated toward a variety of carbon nucleophiles. Treatment of aldehyde 1 with cyanoacetamide, N-benzylcyanoacetamide produced pyridine-3-carboxamides 3 and 4. Treatment of carboxaldehyde 1 with malononitrile dimer and 1H-benzimidazol-2-ylacetonitrile gave 1,6-naphthyridine 5 and pyrido[1,2-a]benzimidazole 6, respectively. Some novel pyrazolo[3,4-b]pyridine 7, pyrido[2,3-d]pyrimidines 8 and 9 were synthesized from the ring opening ring closure reactions of carboxaldehyde 1 with certain heterocyclic enamines. In addition, reaction of carboxaldehyde 1 with certain cyclic enols produced a variety of products. Treatment of carboxaldehyde 1 with 1,3-cyclohexanediones gave xanthene-1,8-diones 19 and 20. Reaction of carboxaldehyde 1 with 5-methyl-2,4-dihydro-3H-pyrazol-3-one proceeds in 1:2 M ratio producing pyrazolo [4 ‘,3 ‘:5,6]pyrano[2,3-c]pyrazole derivative 22. Carboxaldehyde 1 reacted with certain heterocyclic compounds containing active methylene groups to give the corresponding condensation products 22-27. The synthesized compounds were screened in vitro for their antimicrobial activity and showed high to moderate activities against the tested microorganisms.
