  • Efficient method for inversion of secondary alcohols by reaction of chloromethanesulfonates with cesium acetate
    作者:Takeshi Shimizu、Sayoko Hiranuma、Tadashi Nakata
    DOI:10.1016/0040-4039(96)01333-0
    日期:1996.8
    Inversion of a variety of secondary alcohols using the (chloromethylsulfonyl)oxy group as a favorable leaving group with cesium acetate in the presence of 18-crown-6 has been performed to give the inverted acetates in high yields.
    已经进行了使用(氯甲基磺酰基)氧基作为有利的离去基团在18-冠-6存在下用乙酸铯转化各种仲醇的方法,从而以高收率得到了转化的乙酸酯。
  • Stereocontrolled formation of cis and trans ring junctions in hydrindane, decalin, and steroid systems by palladium-catalyzed regioselective and stereospecific hydrogenolysis of allylic formates
    作者:Tadakatsu Mandai、Takaji Matsumoto、Mikio Kawada、Jiro Tsuji
    DOI:10.1016/s0040-4020(01)87264-1
    日期:1993.1
    cis and trans ring junctions can be generated selectively in hydrindane, decalin and steroid systems by the palladium-catalyzed regioselective and stereospecific decarboxylation-hydrogenolysis of allylic formates. The trans junctions were formed from 3β allylic formates of decalin and steroid and 5β allylic formates of hydrindane. The corresponding 3α and 5α formates generate the cis ring junction.
    无论是顺式和反式环结可以选择性地氢化茚,萘烷和类固醇系统由烯丙基甲酸盐的钯催化的区域选择性和立体有择的脱羧-氢解来产生。所述反式结从十氢萘的3β烯丙基甲酸盐和类固醇和氢化茚的5β烯丙基甲酸盐形成。相应的3α和5α晶型生成顺式环结。
  • An efficient method for the reductive transposition of allylic alcohols
    作者:Andrew G Myers、Bin Zheng
    DOI:10.1016/0040-4039(96)00965-3
    日期:1996.7
    Mitsunobu reaction of allylic alcohols with o-nitrobenzenesulfonylhydrazine (NBSH) as nucleophile proceeds at −30 °C with invertive displacement; warming the resultant N-allylic sulfonylhydrazine derivative to 23 °C then leads to allylic diazene formation followed by sigmatropic elimination of dinitrogen. This one-step method for reductive 1,3-transposition is shown to be efficient and highly regio- and
    烯丙基醇与邻硝基苯磺酰基肼(NBSH)亲核试剂的Mitsunobu反应在−30°C下进行反相置换。将所得的N-烯丙基磺酰基肼衍生物加热至23℃,然后导致形成烯丙基二氮烯,然后通过σ消除二氮。这种用于还原性1,3-转移的一步方法显示出在多种烯丙醇底物内均有效且高度区域和立体受控的方法。
  • Hydroxy-steroids. Part XI. The preparation and infrared spectra of vicinal cholestanediols

    Twenty-eight vicinal cholestanediols (positions 1,2; 2,3; 3,4; 4,5; 5,6; 6,7; and 7,8) have been prepared by unambiguous routes starting from the corresponding olefins. The O–H stretching bands of dilute solutions of these diols and of seven reference compounds have been examined under high dispersion. Characteristic differences between ax,ax, ax,eq, and eq,eq compounds were observed. It was concluded
    已经通过从相应的烯烃开始的明确途径制备了二十八个邻位胆固醇二醇(1,2,2,3; 3,4; 4,5; 5,6; 6,7和7,8位)。这些二醇和七种参考化合物的稀溶液的O–H伸缩带已在高分散度下进行了检测。观察到ax,ax,ax,eq和eq,eq化合物之间的特性差异。结论是,不能通过游离和键合羟基的吸收之间的频率差来获得羟基之间的二面角的精确值。
  • Synthesis of Fluorinated Steroids Using a Novel Fluorinating Reagent Tetrabutylammonium Difluorodimethylphenylsilicate (TAMPS)
    作者:Pavel Herrmann、Jaroslav Kvíčala、Vladimír Pouzar、Hana Chodounská
    DOI:10.1135/cccc20081825
    日期:——

    Steroidal 3-fluoroderivatives were prepared from corresponding tosylates using tetrabutylammonium difluorodimethylphenylsilicate as fluorinating agent. The reaction was tested on all four possible C-3 and C-5 stereoisomers of cholestane and 17-oxoandrostane skeletons. In this reaction only one isomer was always formed with opposite configuration at C-3 to starting tosylate. The reaction is accompanied by elimination which affords a mixture of corresponding olefines.

    使用四丁基铵二氟二甲基苯基硅酸酯作为氟化试剂,从相应的tosylates制备了类固醇3-氟衍生物。该反应在胆甾烷和17-氧基雄甾烷骨架的所有四个可能的C-3和C-5立体异构体上进行了测试。在这个反应中,只形成了一个异构体,其C-3位置的构型与起始的tosylate相反。该反应伴随着消除作用,产生相应的烯烃混合物。
