  Synthesis of Five-, Six-, and Seven-Membered Heterocycles by Intramolecular Ring Opening Reactions of 3-Oxetanol Derivatives

  摘要：

  Intramolecular ring opening reactions of 2-phenyl-3-oxetanols have been studied. The starting materials were prepared by the photocycloaddition of benzaldehyde and various silyl enol ethers. The intramolecular nucleophile was either incorporated into the silyl enol ether prior to the Paterno-Buchi reaction (oxetanes 3, 16) or was later installed by functional group interconversion (oxetanes 5. 12). With anionic heteroatom nucleophiles (O, N, S) which were attached to the carbon atom C-3 of the trimethylsilyl-protected oxetanol via an alkyl chain, a substitution at the less substituted position C-4 was observed and the corresponding heterocycles (6, 8, 13, 19) were obtained in moderate to good yields (52-91%). Upon acid catalysis a ring opening of the Boc-protected 3-oxetanol 23 to cyclic carbonates occurred. The reaction did not proceed stereospecifically and resulted in a mixture of diastereomeric products 24 and 25.

  摘要：

  报道了一种新型异双金属 Pd(II)亚砜/(salen)Cr(III)Cl 催化的分子间线性烯丙基 C-H 胺化 (LAA)。该反应直接将密集官能化的 α-烯烃底物（1 当量）转化为线性 (E)-烯丙基氨基甲酸酯，具有良好的产率和出色的区域选择性和立体选择性 (>20:1)。手性双高烯丙基和高烯丙基氧、氮和碳取代的 α-烯烃经过烯丙基 CH 胺化，产率高，选择性好，对映体纯度没有侵蚀。还展示了（E）-烯丙基氨基甲酸酯的流线型路线，可以进一步细化为医学和生物学相关的烯丙胺。有价值的 15N 标记的烯丙胺可以在合成路线的后期阶段通过使用容易获得的 15N-（甲氧基羰基）-对甲苯磺酰胺亲核试剂直接从烯丙基部分生成。有证据表明，该反应是通过异双金属机制进行的，其中 Pd/亚砜介导烯丙基 C-H 裂解以...

  scope and limitations of a tandem intramolecular Nicholas/Pauson−Khand strategy for the synthesis of tricyclic oxygen- and nitrogen-containing heterocycles. This methodology enables conversion of simple acyclic starting materials into a series of previously unknown heterocyclic architectures. For the preparation of cyclic ethers (Z = O), tricyclic [5,6,5]- through [5,9,5]-systems (m = 1, n = 1−4) are available

  我们研究了用于合成三环含氧和氮的杂环的串联分子内Nicholas / Pauson-Khand策略的范围和局限性。这种方法可以将简单的非环状原料转化为一系列先前未知的杂环结构。对于制备环状醚（Z = O），可以使用三环[5,6,5]-到[5,9,5]-系统（m = 1，n = 1-4）和[5,7] ，5]-和[5,8,5]-系统可进行快速有效的合成。可以成功制备含三环[5,7,5]-和[5,8,5]-胺（Z = NTs）的杂环。尝试制造更大的环形系统（Z = O，m = 2; Z = O，n = 5;或Z = NTs，n= 4-5）或通过尼古拉斯与羧酸亲核试剂的反应制备内酯（可通过醇亲核试剂的氧化获得，Z = O）导致分解或二聚。当使用羧酸亲核试剂时，后一种方法能够形成14、16和18元环二醇。我们还研究了在Pauson-Khand步骤中使用手性胺启动子，但未发现不对称诱导。

  Ergot alkaloids and their synthetic analogs have been reported to exhibit broad biological activity. We investigated direct construction of the C/D ring system of ergot alkaloids based on palladium-catalyzed domino cyclization of amino allenes. With this biscyclization as the key step, total synthesis of (+/-)-lysergic acid, (+/-)-lysergol, and (+/-)-isolysergol was achieved.

• A Catalytic, Brønsted Base Strategy for Intermolecular Allylic C−H Amination
  作者：Sean A. Reed、Anthony R. Mazzotti、M. Christina White

  DOI：10.1021/ja903939k

  日期：2009.8.26

  A Bronsted base activation mode for oxidative, Pd(II)/sulfoxide-catalyzed, intermolecular C-H allylic amination is reported. N,N-diisopropylethylamine was found to promote amination of unactivated terminal olefins, forming the corresponding linear allylic amine products with high levels of stereo-, regio-, and chemoselectivity. The predictable and high selectivity of this C-H oxidation method enables late-stage incorporation of nitrogen into advanced synthetic intermediates and natural products.
• Total Synthesis of the Tropoloisoquinoline Alkaloid Pareitropone via Alkynyliodonium Salt Chemistry and Related Studies

  DOI：10.1021/jo026337w

  日期：2002.11.1

  The first chemical synthesis of pareitropone, by a route featuring application of alkynyliodonium salt chemistry, is described. The key transform initiates with addition of an alkylidenecarbene, derived by intramolecular nucleophile addition to the alkynyliodonium moiety, to a proximal aromatic ring. This addition delivers a highly strained norcaradiene substructure that rapidly reorganizes to furnish the pareitropone skeleton.

  日期：2002.10.1

  The synthesis of the tropoloisoquinoline alkaloid pareitropone has been accomplished in 14 steps from 2,3,4-trimethoxybenzoic acid. The key transformations include the generation of an alkylidenecarbene intermediate through intramolecular addition of a tosylamide anion to an alkynyliodonium salt, and the cycloaddition of that carbene to a peri positioned aromatic ring to afford a cycloheptatrienylidene product featuring the intact pareitropone skeleton.
