The microwave-assisted condensation of azepan-4-ones with 3,5-dinitro-1-methylpyridin-2-one in the presence of ammonia was found to be a highly efficient method for the synthesis of nitro-substituted tetrahydropyridoazepines. Variation of the substituent at the amino group enables the regioselective synthesis of tetrahydropyrido[3,2-c]azepines and tetrahydropyrido[2,3-d]azepines.
氨存在下,与3,5-二硝基-1-甲基吡啶-2-酮进行微波辅助缩合反应,被发现是合成硝基取代四氢吡啶并氮杂酮的一种高效方法。氨基上取代基的变化使得能够区域选择性地合成四氢吡啶并[3,2-c]氮杂酮和四氢吡啶并[2,3-d]氮杂酮。
