Application of denitrocyclization reaction for SYNTHESIS OF benzoanylated lactam systems
The synthesis possibility of benzoanylated lactame systems in conditions of denitrocyclisation reaction on the base of the o-nitroaryloxy - and o-nitroarylthioalkylcarbamides containing in the own molecule the additional activating electron-accepting substituent has been studied. From all used variety of initial substrata has been established the only nitryl derivatives of the o-nitroaryloxialkylcarbamides to be suitable for realization of denitrocyclization way.
