(a) 3-(4-Hydroxybenzenesulphonyl)cinnoline A mixture of 2.1 g (0.01 mol) of 3-bromocinnoline, 6.6 g (0.02 mol) of sodium 4-tosyloxybenzenesulphinate and 50ml of dimethylsulphoxide was stirred and heated at -20 C. for 24 hours. The mixture was poured into water and extracted with dichloroethane. The dichloroethane solution was washed with water, dried on anhydrous sodium sulphate and filtered. The solvent was then evaporated with a rotatory evaporator to provide 2.5 g of an oily residue. The desired product was then isolated by chromatography on a silica column using dichlorethane/methanol 98/2. In this manner, 0.45 g of 3-(4-hydroxybenzenesulphonyl)cinnoline was obtained.

TMP-magnesium and TMP-Zinc bases for the regioselective metalation of the cinnoline scaffold

A regioselective functionalization of cinnolines in positions 3 and 8 using metalations has been developed. This involves either the use of a frustrated Lewis pair consisting of BF3¡¤Et2O and TMP 2Mg¡¤2LiCl or the in situ generated base TMP 2Zn¡¤2MgCl2¡¤2LiCl. Successive metalations allow the preparation of 3,8-disubstituted cinnolines. Various functionalizations by acylation, allylation, and cross-coupling reactions with aryl halides or alkenyl iodides were carried out successfully.

SOME REACTIONS OF 3-HALOGENOCINNOLINES CATALYSED BY PALLADIUM COMPOUNDS

3-Bromo-or 3-iodo-cinnoline (and 4-substituted analogues ) are condensed with terminal alkynes in the presence of Pd and Cu compounds as catalysts to give the 3-alkynyl-derivatives.When 4-chloro- or 4-phenoxy-compounds are used, the products react with amines, in the presence of copper(I) iodide, to form pyrrolo<3,2-c>cinnolines and with hydrazines to give either the same ring system or a pyrazolo<4,3-c>cinnoline.Hydrolysis of 3-alkynyl-4phenoxycinnoline to 3-alkynyl-4(1H)-cinnolinone, followed by cyclisation, yields the furo<3,2-c>cinnoline.Attempts to condense 3-halogenocinnolines with alkenes gave variable results: 3-phenyl ethenyl- and 3(2-pyridylethenyl)-4-(1H)-cinnolinones were obtained but 3-bromocinnoline gave the 3,3′-bicinnolinyl.Action of palladium acetate in the presence of ethyl acrylate converted 3-bromo-4-phenoxycinnoline into benzofuro<3,2-c>cinnoline and 3-bromo-4-phenylaminocinnoline into indolo<3,2-c>cinnoline.

The mixture was poured into water and extracted with dichloroethane. The dichloroethane solution was washed with water, dried on anhydrous sodium sulphate and filtered. The solvent was then evaporated with a rotatory evaporator to provide 2.5 g of an oily residue. The desired product was then isolated by chromatography on a silica column using dichlorethane/methanol 98/2. In this manner, 0.45 g of 3-(4-hydroxybenzenesulphonyl)cinnoline was obtained.
