Unsubstituted cyclic imides were synthesized from a series of cyclic anhydrides,hydroxylamine hydrochloride (NH2OH·HCl), and 4-N,N-dimethylamino-pyridine (DMAP,base catalyst) under microwave irradiation in monomode and multimode microwaves. Thisnovel microwave synthesis produced high yields of the unsubstituted cyclic imides forboth the monomode (61 - 81%) and multimode (84 - 97%) microwaves.
未取代的环状亚胺通过一系列环状酐、盐酸羟胺(NH2OH·HCl)以及4-N,N-二甲氨基吡啶(DMAP,碱催化剂)在单模和多模微波辐照下合成。这种新颖的微波合成方法在单模微波(产率61%-81%)和多模微波(产率84%-97%)条件下均能产生高产量的未取代环状亚胺。
