Oxygen‐bridged monastrol analogs, 13‐acetyl‐9‐methyl‐11‐oxo(or thioxo)‐8‐oxa‐10,12‐diazatricyclo[7.3. 1.02,7]trideca‐2,4,6‐trienes, were synthesized by one‐pot three component condensation reaction of substituted salicylaldehyde, acetylacetone and urea or thiourea with nontoxic, inexpensive, and easily available NaHSO4 as catalyst under microwave irradiation and solvent‐free conditions in short time with good
氧桥蒙纳斯特类似物13-乙酰基-9-甲基-11-氧代(或thioxo)-8-氧代-10,12-二氮杂三环[7.3。1.0 2,7 ] trideca-2,4,6-三烯是通过取代的水杨醛,乙酰丙酮和尿素或硫脲的一锅三组分缩合反应与无毒,廉价且易于获得的NaHSO 4作为催化剂在微波辐射下合成的。短时间内无溶剂,收率高。产物的结构通过IR,1 H NMR,13 C NMR光谱和元素分析来表征。
