  Ammonium Eneselenolates:  Stereochemistry and Electronic Properties

  摘要：

  Ammonium eneselenolates were generated with high efficiency by reacting selenothioic acid S-esters with a THF solution of TBAF. The methylation of ammonium eneselenolates gave ketene selenothioacetals as stereoisomeric mixtures. The ratio of the two stereoisomers depended on the duration of the reaction before the addition of Mel. Ammonium eneselenolates were characterized by examining their H-1, C-13, and Se-77 NMR spectra, which indicated that ammonium eneselenolates were present almost exclusively as Z-isomers. These results suggested that ammonium eneselenolates are kinetically generated as stereoisomeric mixtures, and isomerization of E-isomers to Z-isomers then takes place to result in the exclusive formation of Z-isomers. During the methylation of Z-isomers of ammonium eneselenolates, the isomerization of Z-isomers to E-isomers occurs to give stereoisomeric mixtures of ketene selenothioacetals. NMR spectra of ammonium eneselenolates implied that the electrons at the selenium atom are somewhat delocalized to the carbon-carbon double bond and the carbon-selenium bond shows partial double-bond character.

  Selenothioic acid S-alkyl esters were reacted with allylic bromides in the presence of Et3N. Mono-, di- or tri-allylatd products were selectively formed by changing reaction temperatures, times and allylic bromides used. The reaction proceeded with high regio- and stereoselectivity via the seleno-Claisen rearrangement. The selective synthesis of monoallylated esters was also attained by the reaction

  在Et 3 N存在下，使硒代硫代酸S-烷基酯与烯丙基溴反应。通过改变反应温度，时间和所用的烯丙基溴选择性地形成单，二或三烯丙基的产物。该反应通过seleno-Claisen重排以高度的区域选择性和立体选择性进行。还可以通过原位生成的烯醇硒酸锂与烯丙基溴的反应来实现单烯丙基化酯的选择性合成。

  Allylations of selenothioic acid S-alkyl esters with allylic bromides in the presence of Et3N in THF took place selectively at the α-position of selenocarbonyl group to give allylated products with high regio- and stereo-selectivity.
