It was shown that initial protonation of 9-aminomethylene-4-azafluorene takes place at the pyridine nitrogen atom. In nitrosation of this azafluorene, 4-azafluorenone oxime is formed, and in reaction with dichlorocarbene, 1'-amino-2', 2'-dichlorospiro[4-azafluorene-9,3'-cyclopropane] is formed. Acylation yields mono- or diacyl derivatives as a function of the acylating agent and reaction conditions. |
