A novel 7, 9, 11-trimethyl-8,10,12-trioxatetracyclo[5.3.2.0.4,9.04,11]-dodec-1-yl]-2-butanone skeleton 3 has been synthesized by the treatment of 2-acetyl-3,4-dihydro-2,5-di (3″-oxo-butyl)-6-methyl-(2H)-pyran 2, with H-ZSM-5. However, the treatment of compound 2 with p-TsOH gives bibenzyls. Present report provides a unique acid catalysed cyclization of diketo-olefin system over zeolite, X-ray crystal
新颖的7、9、11-三甲基-8,10,12-三氧杂环己烷[5.3.2.0。4,9 0.0 4,11 ] -十二碳-1-基] -2-丁酮骨架3已经由2-乙酰基-3,4-二氢-2,5-二的处理(3“ -氧代-合成丁基)-6-甲基-(2H)-吡喃2和H-ZSM-5。但是,用对-TsOH处理化合物2得到联苄基。本报告提供了在沸石上二酮-烯烃体系的独特的酸催化环化反应,还给出了3的X射线晶体结构。
