  • Alkylidenesilacyclopropanes Derived from Allenes: Applications to the Selective Synthesis of Triols and Homoallylic Alcohols

    transfer to allenes. Oxasilacyclopentanes derived from allenes were prepared with high regio- and diastereoselectivity by a two-step, one-flask silacyclopropanation/carbonyl insertion reaction. Triols and homoallylic alcohols were formed diastereoselectively by functionalizing the oxasilacyclopentanes. An optically active allene (>98% ee) was utilized to synthesize an enantiopure homoallylic alcohol in 96%

    Gold and silver: A 1:2 mixture of [(S)‐1}(AuCl)2] and AgBF4 catalyzes the enantioselective hydroamination of chiral, racemic 1,3‐disubstituted allenes with N‐unsubstituted carbamates to form N‐allylic carbamates in good yield, with high regio‐ and diastereoselectivity, and up to 92 % ee (see scheme, Cbz=benzyloxycarbonyl).

    reactions were conducted with cobalt catalysts containing bisphosphines with large bite angles (e.g. 111° for xantphos and 114° for Nixantphos). A range of internal allenes underwent these Co-catalyzed hydroboration reactions in a regiodivergent manner to yield the corresponding (Z)-alkenylboronates in high isolated yields and with high regioselectivity. These reactions show good functional group compatibility
    我们报道了在由实验室稳定的 Co(acac) 2和双膦配体生成的催化剂存在下,芳基、烷基二取代的内丙二烯频那醇硼烷 (HBpin) 的立体选择性区域发散氢化反应。确定了该氢化反应的区域选择性与双膦配体的咬角之间的有趣相关性。当使用含有中等咬角(例如dppb为98°,dppf为96°)的双膦催化剂进行氢化时,HBpin选择性地加成到烷基取代的双键上。然而,当使用含有大咬角(例如xantphos为111°,Nixantphos为114°)双膦催化剂进行反应时,HBpin选择性地加成到芳基取代的双键上。一系列内丙二烯以区域发散的方式经历这些共催化的氢化反应,以高分离产率和高区域选择性产生相应的( Z )-烯基硼酸酯。这些反应表现出良好的官能团相容性,并且无需使用干燥箱即可轻松放大至克级。此外,相同丙二烯底物的催化氢化硅烷化和氢化反应之间的区域选择性的比较表明,丙二烯的这种
  • Synthesis of allenes via thermal cycloreversion of .alpha.-alkylidene-.beta.-lactones
    作者:Rick L. Danheiser、Yong Mi Choi、Maria Menichincheri、Eric J. Stoner
    DOI:10.1021/jo00054a011
    日期:1993.1
    This paper describes the application of the solution-phase [2 + 2] cycloreversion of alpha-alkylidene-beta-lactones as a practical method for the generation of substituted allenes. Upon heating in dimethylformamide solution at 110-125-degrees-C, these unsaturated beta-lactone derivatives undergo decarboxylation to provide allenes in good to excellent yield. Alpha-alkylidene-beta-lactones are conveniently prepared via the phenylselenylation of beta-lactone enolates followed by oxidative elimination of the resulting alpha-phenylseleno derivatives. The beta-lactone starting materials are synthesized by the addition of thiol ester enolates to ketones and aldehydes according to our recently reported procedure.
  • Toxicity of Pumiliotoxin 251D and Synthetic Analogs to the Cotton Pest Heliothis virescens
    作者:Thomas M. Bargar、Renee M. Lett、Peter L. Johnson、James E. Hunter、C. P. Chang、Daniel J. Pernich、Mark R. Sabol、Michael R. Dick
    DOI:10.1021/jf00052a037
    日期:1995.4
    A series of 13 simplified analogs of frog skin derived pumiliotoxin indolizidine alkaloids was prepared and evaluated for their toxicity to the larvae of the important cotton pest Heliothis virescens. The alkyl side chain of pumiliotoxin 251D was replaced with a variety of substituents designed to influence or restrict-its conformation and its ability to act as a site of metabolic detoxification. Significantly, a substituent in the R configuration at the C-2' carbon of the side chain was required for toxicity. Computational studies suggested that this substituent may control the active conformation of the side chain. No structural modification led to a significant improvement in toxicity over the natural product.
