Under the mild condition, allyl bromide/Zn mediated reductive N,O-diallylat
ion of nitrobenzene was observed. In case of o-nitroarenes such as 2-nitrob
enzaldehyde derivatives, 2'-nitroacetophenone, and N-(2-nitrobenzylidene)an
ilines, reductive cyclizations were accomplished in good to excellent yield
s. Synthesis and mechanistic details are discussed.
