The synthesis of six new examples of 2,8-dinitro-substituted Troger'sbaseanalogues are reported, together with the first examples of 1,7-, 3,9- and 4,10-dinitro Troger'sbaseanalogues and the first example of a tetranitro Troger'sbase compound. Several of these dinitro compounds lack substituents at the 2- and 8-positions and therefore provide further examples of Troger'sbaseanalogues derived
An efficient and one-pot synthetic method for the regioselective ortho-nitration of the N-phenyl carboxamides and primary anilines has been developed by using bismuth nitrate and aceticanhydride as the nitrating reagents. Reaction proceeds at room temperature and results in corresponding ortho-nitrated products in moderate to excellent yields. This method provides an operationally simple, regioselective
