J. Deutsch et Hj. Niclas, A CONVENIENT PROCEDURE FOR THE FORMYLATION OF AMINES AND ALCOHOLS USING CYANOMETHYL FORMATE, Synthetic communications, 23(11), 1993, pp. 1561-1568
A simple method for the direct formylation of amines using cyanomethyl
formate is described. The formylation succeeds in moderate to high yi
elds under mild and neutral conditions. Thus, formamides 2a-f, 2i-m ar
e obtained at room temperature. A chemoselective N-formylation is achi
eved in the case of ethanolamine. The formylation of nitroanilines and
the O-formylation of alcohols only succeeds in the presence of a cata
lytic amount of imidazole leading to 2g,h and 3a-e, respectively.
