Synthesis of new derivatives of 3-azabicyclo[3.3.1]nonan based on N-(2-hydroxy-3,5-dinitrophenyl)benzamide

Abstract

Methods for the synthesis of 3-methyl-N-(1,5-dinitro-8-oxo-3-azabicyclo[3.3.1]non-6-en-7-yl)benzamide and 10-methyl-4-phenyl-1,8-dinitro-3-oxa-5,10-diazatricyclo[6.3.1.02.6]dodeca-2(6),4-diene from N-(2-hydroxy-3,5-dinitrophenyl)benzamide by Mannich condensation of the corresponding σ-adducts was developed. It is shown that the obtained substances can interconvert to each other under certain conditions.
