On August 31, 2012, Xu, Shao-hong published an article.Quality Control of Ethyl indolizine-1-carboxylate The title of the article was Iron-catalysed C-3 functionalization of indolizines via C-H bond cleavage. And the article contained the following:
The synthesis of 3,3′-(arylmethylene)diindolizine with a FeCl3.6H2O catalyst was achieved with excellent efficiency at room temperature Various indolizines were prepared by the reaction with either aromatic or aliphatic aldehydes to produce di- or triheteroarylmethanes. The experimental process involved the reaction of Ethyl indolizine-1-carboxylate(cas: 93476-46-1).Quality Control of Ethyl indolizine-1-carboxylate
The Article related to indolizine aldehyde electrophilic substitution carbon hydrogen bond cleavage, arylmethylene diindolizine preparation iron catalyst, Heterocyclic Compounds (One Hetero Atom): Quinolines and Isoquinolines and other aspects.Quality Control of Ethyl indolizine-1-carboxylate
