In this Letter we present the synthesis of hitherto unreported 1-aryl-2-alkyl-1,4,5,6,7,8-hexahydro-1,3-diazocines 1. Cyclic amidines 1 were synthesized by PPSE promoted ring closure of N-acyl-N′-arylpentamethylenediamines 2. The cyclodehydration reaction was performed under microwave irradiation in solvent-free conditions. Precursors 2 were prepared by selective functionalization of N-arylcadaverines
在这种信我们提出迄今未报告的1-芳基-2-烷基-1,4,5,6,7,8-六氢-1,3- diazocines的合成1。环脒1合成由PPSE促进了环闭合N-酰基Ñ '-arylpentamethylenediamines 2。在无溶剂条件下在微波辐射下进行环脱水反应。前体2通过选择性官能化N-芳基尸胺3制备。
