  • Sc(OTf)3-catalyzed diastereoselective Friedel–Crafts reactions of arenes and hetarenes with 3-phenylglycidates
    作者:David Wilcke、Thorsten Bach
    DOI:10.1039/c2ob25988e
    日期:——
    Five different para-substituted 3-phenylglycidates (3-phenyloxirane-2-carboxylates) were prepared and subjected to reactions with arenes and hetarenes under Lewis acid catalysis. Sc(OTf)3 was found to effectively (5 mol%) promote a Friedel–Crafts reaction in nitromethane as the solvent. The reaction was shown to proceed stereoconvergently, which makes the intermediacy of a benzylic cation likely. The diastereoselectivities varied depending on the choice of the nucleophile and 3-arylglycidate. Best results were obtained with tert-butyl 3-anisylglycidate, which delivered the respective products with high syn-preference in diastereomeric ratios (d.r.) between 82 : 18 and >95 : 5. The observed selectivity can be explained by a model, according to which the intermediate benzylic cations adopt a preferred conformation, which allows for diastereoface-differentiation by the adjacent stereogenic center.
    制备了五种不同的对位取代3-苯基缩水甘油酸酯(3-苯基环氧乙烷-2-羧酸酯),并使其在Lewis酸催化下与芳烃和杂芳烃反应。发现Sc(OTf)3能有效(5摩尔%)促进以硝基甲烷为溶剂的Friedel-Crafts反应。反应呈现立体汇聚性,这表明可能存在苄基阳离子中间体。对映选择性因亲核试剂和3-芳基缩水甘油酸酯的选择而异。使用叔丁基3-茴香基缩水甘油酸酯时效果最佳,产物的顺-偏好性在外消旋体比例(d.r.)介于82:18至>95:5之间。观察到的选择性可通过一个模型解释,该模型表明中间体苄基阳离子采取的优先构象允许相邻的手性中心进行对映面区分。
  • Enantioselective catalytic epoxidation of cinnamate esters
    作者:Eric N. Jacobsen、Li Deng、Yoshiro Furukawa、Luis E. Martínez
    DOI:10.1016/s0040-4020(01)89369-8
    日期:1994.4
    A broad study of the (salen)Mn(III)-catalyzed asymmetric epoxidation of cis-cinnamate esters reveals that the steric properties of the ester group have a profound influence on enantioselectivity in the epoxidation reaction, with bulkier esters affording highest ee's. The sensitivity of the reaction selectivity to the steric properties of the cis-alkene are consistent with a “skewed” side-on approach
    对(salen)Mn(III)催化的顺式肉桂酸酯不对称环氧化的广泛研究表明,酯基的空间性质对环氧化反应中的对映选择性有深远的影响,较大的酯具有最高的ee。反应选择性对顺式烯烃的空间敏感性的敏感性与烯烃对金属-羰基的“偏斜”侧接方法一致。底物芳烃环取代基的电子性质与环氧化ee不相关,而与产物形成的顺式/反式分配相关。提供了逐步氧原子转移机理中非极性中间体的证据。吡啶N的存在氧化物衍生物对催化剂的速率和总周转率有重大影响,但对环氧化的立体选择性的影响可忽略不计。提出了这些添加剂作用的机理基础。地尔硫卓的高度对映选择性合成说明了肉桂酸酯环氧化方法的合成适用性。

    An effective new route to diltiazem, a representative coronary vasodilator, through (-)-(2R, 3S)-3-(4-methoxyphenyl)glycidamide [(-)-2] has been achieved. The glycidamide (-)-2 was prepared in 43% overall yield by a combination of the enzymatic resolution of methyl (±)-(2RS, 3SR)-3-(4-methoxyphenyl)glycidate [(±)-1] with lipase and the following amidation of (-)-1 with ammonia. A one-pot synthesis through the treatment of (-)-2 with 2-aminothiophenol and a following ring closing reaction efficiently gave a key intermediate of diltiazem synthesis, (2S, 3S)-2, 3-dihydro-3-hydroxy-2-(4-methoxyphenyl)-1, 5-benzothiazepin-4(5H)-one [cis-(+)-5] in 80% overall yield.
    已经通过(-)-(2R,3S)-3-(4-甲氧基苯基)缩水甘油酰胺[(-)-2]实现了一种有效的新途径地尔硫卓(一种代表性的冠状血管扩张剂)。通过结合 (±)-(2RS, 3SR)-3-(4-甲氧基苯基)缩水甘油酸酯 [(±)-1] 与脂肪酶的酶解,制备出缩水甘油酰胺 (-)-2,总产率为 43%以及以下(-)-1与氨的酰胺化。通过用 2-氨基苯硫酚处理 (-)-2 和随后的闭环反应,一锅合成有效地得到了地尔硫卓合成的关键中间体 (2S, 3S)-2, 3-二氢-3-羟基-2 -(4-甲氧基苯基)-1, 5-苯并硫氮杂卓-4(5H)-酮[顺式-(+)-5],总收率80%。
  • Highly Efficient Darzens Reactions Mediated by Phosphazene Bases under Mild Conditions
    作者:Carmine Lops、Paolo Pengo、Lucia Pasquato
    DOI:10.1002/open.202200179
    日期:2022.10
    The first Darzens reaction of α-halo acetate esters with aromatic aldehydes promoted by phosphazene bases is reported. The reactions proceed smoothly, affording α,β-epoxy esters in nearly quantitative yields, short time, and no side products. The phosphazene base P1-t-Bu can be used with aldehydes carrying electron-withdrawing groups, while the base P4-t-Bu is preferable when the aldehydes carry electron
    报道了磷腈碱促进的 α-卤代乙酸酯与芳香醛的第一个 Darzens 反应。反应进行顺利,以接近定量的收率、短时间得到α, β-环氧酯,且无副产物。磷腈碱P 1 - t -Bu可以与带有吸电子基团的醛一起使用,而当醛带有给电子取代基时,优选碱P 4 - t -Bu。
