项目摘要
The followings are new results developed by the present project. 1. Direct synthesis of thiiranes from alkenes using 4,4'-oligothiodimorpholines in the presence of Bronsted acid or metal triflate was investigated. Thus,2-adamantylidene-9-benzonorbornenylidene 1 reacted with 4,4'-teirathiodimorpholine 2, 4,4'-dithiodimorpboline 3, and 4,4'-thiodimorpholine 4 in the presence of carboxylic acid or ptoluenesulfonic acid to give the corresponding thiiranes. When carboxylic acid was used, the rate of reaction was faster as its pK_a value was smaller. Unfortunately, isomerization and decomposition of the resulting thiirane was observed in most of the reactions. Reactivity of 4,4'-oligothiodimorpholiws toward 1 is found to be 2> 3> 4. 2. The direct synthesis of thiiranes using 4,4'-dithiodimorpholine 3 and arid anhydride was investigated. Although reactions of 1 and 3 with highly reactive acid anhydride such as Tf_2O, TfOAc, Ts_2O, and (CF_3C0)_2O took place to form the corresponding thiiranes in moderate yields, their isomerization and decomposition also occurred. The reaction with excess of Ac_2O proceeded to give the thiiranes without the isomerization and decomposition of the products. 2,2'-Biadamantylidene 5, and trans- and cis-cyclooctene, 6 and 7, also reacted to furnish the corresponding thiiranes under the same conditions. 3. The direct synthesis of thiiranes using N, N-dithiobisazoles was investigated. Although the reaction of 1 with N, N-Dithiobisbenzimidazole 8 in the absence of Cu (Otf)_2 and Sc (Otf)_3 did not occur, that with N,N-dithiobis (1H-1,2,4-triazole) 9 proceeded even at-15℃. The alkenes 5-7, norbornene, and anti- and syn-9,9'-bibenzonorbomenylidenes, 8 and 9 also reacted to furnish the corresponding thiiranes with retention of configuration of the alkenes under the same conditions.
以下是本项目取得的新成果。1.研究了在Bronsted酸或金属三氟化钠存在下,4,4‘-低聚硫二吗啉催化烯烃直接合成硫杂环己烷的反应。因此,在羧酸或对甲苯磺酸存在下,2-金刚烷-9-苯甲醛-1与4,4‘-硫代二吗啉2,4,4’-二硫代二吗啉3和4,4‘-硫代二吗啉4反应生成相应的硫杂环。当使用羧酸时,反应速度较快,pK_a值较小。不幸的是,在大多数反应中都观察到了生成的硫杂环己烷的异构化和分解。4,4‘-低聚硫二吗啉与1的反应活性为2>;3>;4.2。研究了4,4’-二硫代二吗啉3与脱水酸酐直接合成硫杂环己烷的反应。1和3与高活性酸酐如Tf_2O、TfOAc、TS_2O和(Cf_3C0)_2O反应生成相应的硫杂环,产率适中,但它们也发生了异构化和分解。过量的Ac_2O继续反应生成硫杂环,而不发生异构化和分解。在相同条件下,2,2‘-联金刚烷5和反式和顺式环辛烯6和7也反应生成相应的硫杂环。3.研究了N,N-二硫代二氮唑直接合成硫杂环己烷的反应条件。尽管在没有铜(OTf)_2和Sc(OTf)_3的情况下,1与N,N-二硫双苯并咪唑8没有发生反应,但即使在-15℃时,与N,N-二硫双(1H-1,2,4-三唑)9的反应仍在进行。在相同的条件下,5-7烯烃、降冰片烯、反式和合成-9,9‘-联苯并苯亚甲基、8和9也反应生成相应的硫杂环并保持其构型不变。
