Microwave-assisted regioselective synthesis of 2,4-disubstituted imidazoles: Nortopsentin D synthesized by minimal effort
Fresneda,Molina,Sanz
, p. 218 - 221 (2001)
A two step regioselective synthesis of 2,4-disubstituted imidazoles based on the reaction of α-azidoacetyl indoles with carboxylic acids in the presence of tertiary phosphines followed by cyclization of the resulting ketoamides by the action of ammonium acetate under microwave irradiation is described. The method has successfully been applied to the synthesis of the antifungal nortopsentin D [2,4-bis(3-indolyl)imidazole].
