3,6-Dichloropyridazine and 1-alkyl-3,6-dichloropyridazinium cations react with pyrrolylmagnesium bromide to produce 3-chloro-6-(2-pyrrolyl)pyridazine. Further reaction with other nucleophiles is slow, but is enhanced by quaternisation of the 2-N atom

The Stetter procedure has been adapted to produce simple 2-furyl- and 2-thienylpyridines and their related oligomers, which have been characterised by 13 C NMR spectroscopy. σ values for the 2-furyl and 2-thienyl rings have been deduced from the pK

The title compound, 2, and its 2-methyl salt, 8, have been synthesised from methyl 1,4-dihydro-4-methylpyrrolo[3,2-b]indole-2-carboxylate. The pKa of the conjugate acid 2 is similar to those of ellipticine and its 9-hydroxy and 9-methoxy derivatives,

The Stetter procedure has been adapted to produce oligomeric and polymeric pyrrolylpyridines, which have been characterised by 13 C NMR spectroscopy. The lower activity of 2-(pyrrol-2-yl)pyridines towards quaternisation permits selective N-alkylation

A theoretical study of the transition structures for the reactions of 1-methyl-2-vinylpyrrole 1 with methyl propiolate (MP) and with dimethyl acetylenedicarboxylate (DMAD) indicates that, for this vinyl system, the factor controlling the different co

A theoretical study of the transition structure for the electrophilic attack step of the 1-methyl-2-vinylpyrrole to dimethyl acetylenedicarboxylate is reported with analytical gradients at AM1 and PM3 semi-empirical levels and ab initio at 3-21G leve
