本文探索了以4a,10a-二氰基-1,2,3,4,4a,4b,5,6,7,8,10,10a-十二氢-1,4-二羰基菲为底物,对甲苯磺酸作催化剂,2-甲基-2-乙基1,3-二恶烷做试剂,在羰基保护常用溶剂中的行为。结果在常用溶剂苯,甲苯,二氯甲烷,甲醇,二氯甲烷-甲醇,离子液体(bmim)HSO4),乙二醇中基本不反应,然而在吡啶中可以完全转化并得到相对较好的收率。 This paper explored the use of 4a, 10a-dicyano-1,2,3,4,4a, 4b, 5,6,7,8,10,10a-dodecahydro-1,4-dicarbonylphenanthrene as a substrate , P-toluenesulfonic acid as catalyst, 2-methyl-2-ethyl-1, 3-dioxane as a reagent in the protection of carbonyl solvents commonly used behavior. The results are essentially non-reactive in common solvents benzene, toluene, methylene chloride, methanol, methylene chloride-methanol, bimodal HSO4) and ethylene glycol but completely converted in pyridine and give relatively good yields rate.
