P. Marjani et al. Introduction The formyl group is one of the most important groups for the protection of amines [1]. Formamides, the corresponding products, are important intermediates which have been widely applied in the synthesis of fine chemicals [2, 3] and pharmaceutically important compounds such as fluoroquinolines [4], imidazoles [2], 1,2-dihydroquinolines [5], nitrogen-bridged heterocycles [6], oxazolidinones [7], and cancer chemotherapeutic agents [8]. Also, formamides are applied as catalysts in the allylation [9], hydrosilylation [10] and reaction of carbonyl compounds. They are used as reagents in Vilsmeier formylation [11] and in the synthesis of formamidines and isocyanides [12]. A large number of methods have been reported for the N-formylation of amines [13–22], but most of them suffer from major drawbacks such as thermal instability, sensitivity to moisture, application of toxic and expensive formylating agents and catalysts, high temperatures, prolonged reaction http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
