    Improved Enantioselectivity in the Epoxidation of Cinnamic Acid Derivatives with Dioxiranes from Keto Bile Acids
    摘要:
    The asymmetric epoxidation of substituted cinnamic acids has been obtained in the presence of different keto bile acid derivatives as optically active carbonyl inducers and Oxone as oxygen source. Predominant or almost exclusive formation of both enantiomeric epoxides is obtained (ee up to 95%) depending on the specific substitution at carbons C(7) and C(12) of the bile acid.

  • Chemoselective Oxidation of Equatorial Alcohols with N-Ligated λ<sup>3</sup>-Iodanes
    作者:Myriam Mikhael、Sophia A. Adler、Sarah E. Wengryniuk

    of nitrogen-ligated (bis)cationic λ3-iodanes (N-HVIs) for alcohol oxidation and their unprecedented levels of selectivity for the oxidation of equatorial over axial alcohols. The conditions are mild, and the simple pyridine-ligated reagent (Py-HVI) is readily synthesized from commercial PhI(OAc)2 and can be either isolated or generated in situ. Conformational selectivity is demonstrated in both flexible
    复杂多元醇中醇的位点选择性和化学选择性官能化仍然是一个艰巨的合成挑战。尽管在氧中心的选择性衍生化方面已取得重大进展,但化学选择性氧化为相应的羰基的进展却很少。在循环系统中,虽然对轴型醇的选择性氧化是众所周知的,但尚未报道互补的赤道选择性过程。本文中,我们报道了氮连接的(双)阳离子λ3-碘(N-HVIs)在醇氧化中的应用以及它们对赤道醇与轴向醇的氧化选择性的空前水平。条件温和,简单的吡啶连接试剂(Py-HVI)可以很容易地从商业PhI(OAc)2合成,可以分离或原位生成。

    bile acids (IIa-d), their methyl esters (IIe-h), and their formylated derivatives (IIi-k) were synthesized and their reduction investigated by both catalytic and chemical methods as an alternative route to the synthesis of allo bile acids. Lithium-ammonia reduction proved to be the better method for the reduction of these 1,4-dien-3-ones producing the 3-keto- and 3 beta-hydroxy-allo bile acids (Vb-d)
    合成了各种胆汁酸 (IIa-d) 的 1,4-Dien-3-ones、它们的甲酯 (IIe-h) 和它们的甲酰化衍生物 (IIi-k),并通过催化和化学方法研究了它们的还原情况,如合成别胆汁酸的另一种途径。锂-氨还原被证明是还原这些 1,4-二烯-3-酮的更好方法,产生 3-酮-和 3-β-羟基-别胆酸 (Vb-d) 和 (VIb-d)产率为 66-72%。

    日期:1980.4
    Chenodeoxycholic acid was converted to a new 5,14-epi-28,30-dinorquassinoid analog. Two isomeric A-ring diosphenol acetate derivatives of deoxycholic acid were synthesized. A 3-oxo-5 beta-steroid was transformed to a 4-acetoxy-3-oxo-delta 4-steroid by treatment with base and oxygen or to a 2-acetoxy-3-oxo-delta 2-steroid by reaction with cupric chloride in refluxing acetic acid followed by acetylation
