1-Benzyl-2-(ethoxycarbonyllmethylene)-2,3,4,5-tetrahydroimidazole undergoes preferred C-alkylation with halogenonakanes, dihalogenoalkanes and epoxides: subsequent removal of of the ethoxycarbonyl group provides a new route to 2-alkyl-4,5-dihydroimidazoles. 1,3-Dihalogenoalkanes afford imidazo[1,2-a]pyridines via C,N-dialkylation.
A New Sequence for the Cα-Alkylation of 4,5-Dihydroimidazoles
Jones, Raymond, C. F.,Hirst, Simon C,Turner, Ian
, p. 953 - 954 (2007/10/02)
The C-alkylation of 1-benzyl-2-(ethoxycarbonylmethylene)-2,3,4,5-tetrahydroimidazole with halogeno- and dihalogeno-alkanes is described; subsequent removal of the ethoxycarbonyl group provides a new route to 2-alkyl-4,5-dihydroimidazoles. 1,3-Dihalogenoalkanes afford imidazopyridines.
Dihydroimidazoles in Synthesis: C-Alkylation of 1-Benzyl-2-(α-lithioalkyl)-4,5-dihydroimidazoles and a Synthesis of Alkanoic Acids
Anderson, Michael W.,Jones, Raymond C. F.,Saunders, John
, p. 205 - 210 (2007/10/02)
1-Benzyl-2-alkyl-4,5-dihydroimidazoles have been (laterally) metallated and C-alkylated by reaction with alkyl halides and an epoxide; intramolecular C-alkylation has led to a tetrahydro-5H-pyrroloimidazole.Hydrolysis of the 4,5-dihydroimidazoles to produce alkanoic acids completes a homologation sequence.
