    Asymmetric intramolecular cyclopropanation of diazo compounds with metallosalen complexes as catalyst: structural tuning of salen ligand
    摘要:
    Intramolecular cyclopropanation of alkenyl alpha-diazoacetates and alkenyl diazomethyl ketones was examined by using optically active (ON+)Ru(11)(salen) and Co(II)(salen) complexes as catalysts. For the cyclization of 2-alkenyl alpha-diazoacetates, Co(II)(salen) complexes 9 and 10 were found to be superior catalysts to the corresponding (ON+)Ru(11)(salen) complexes 4 and 5. On the other hand, (ON+)Ru(II)(salen) complex 2 was found to be the catalyst of choice for the cyclization of 3-alkenyl diazomethyl ketones, and complex 4 was found to be a good catalyst for the cyclization of (E)-4-alkenyl diazomethyl ketones. The present study demonstrates that metallosalen complexes, especially optically active (ON+)Ru(II)(salen) and Co(11)(salen) complexes, can serve as efficient catalysts for the cyclization of alkenyl diazocarbonyl compounds, if a suitable salen ligand is used as the chiral auxiliary.

  • A convenient one-pot synthesis of homoallylic halides and 1,3-butadienes
    作者:Ken-Tsung Wong、Ying-Yueh Hung
    DOI:10.1016/j.tetlet.2003.07.006
    日期:2003.10
    An efficient one-pot synthetic pathway for the preparation of homoallylic halides by in situ generated MgBrCl-promoted ring opening of cyclopropylcarbinyl acetates has been established. An easily accessible one-pot synthetic protocol of 1,3-butadienes by the elimination of hydrogen halides from the resulting homoallylic halides in the presence of an excess amount of strong base has also been developed

  • Selective Reduction of Barbituric Acids Using SmI<sub>2</sub>/H<sub>2</sub>O: Synthesis, Reactivity, and Structural Analysis of Tetrahedral Adducts

    Making a mark: Since the 1864 landmark discovery by Adolf von Baeyer, barbituric acids have played a prominent role in organic synthesis. Herein, the first chemoselective monoreduction of barbituric acids to the corresponding hemiaminals is described. The method delivers mono‐ and bicyclic hemiaminal products by a general single‐electron‐transfer polarity reversal mechanism.

    esters and lactones have long been thought to lie outside the reducing range of SmI(2), activation of the lanthanide reagent by H(2)O allows some of these substrates to be manipulated in an unprecedented fashion. For example, the SmI(2)-H(2)O reducing system shows complete selectivity for the reduction of 6-membered lactones over other classes of lactones and esters. The kinetics of reduction has been
    尽管长期以来一直认为简单的脂肪族酯和内酯位于 SmI(2) 的降低范围之外,但 H(2)O 对镧系元素试剂的激活允许以前所未有的方式操纵其中的一些底物。例如,SmI(2)-H(2)O 还原系统显示出相对于其他类别的内酯和酯还原 6 元内酯的完全选择性。使用停流分光光度法研究了还原动力学。实验和计算研究表明选择性的起源在于初始电子转移到内酯羰基。在用 SmI(2)-H(2)O 进行内酯还原过程中形成的自由基中间体可用于环化,以提供具有高非对映选择性的环状酮(或缩酮)产品。
