  Synthesis, crystal structure and reactivity studies of iron complexes with pybox ligands

  摘要：

  Iron(II) complexes, [Fe(2,6-bis(4,4-dimethyl-1,3-oxazolin-2-yl)pyridine)Cl-2] ((Fe(Me-2-pybox)Cl-2), 3) and [Fe(2,6-bis(4,4-diphenyl-1,3-oxazolin-2-yl)pyridine)Cl-2] ((Fe(Ph-2-pybox)Cl-2), 4), have been synthesized and characterized by X-ray crystallographic analysis. Upon treatment of complex 3 with silver triflate and 4 with acetonitrile, [Fe(Me-2-pybox)(CH3CN)OTf2] (5) and [Fe(Ph-2-pybox)(CH3CN)(2)Cl][FeCl3] (6) were obtained, respectively. The bulkier phenyl substitutes were found not only to cause the elongation of the N-Fe bonds but also influence the reactivity of the Fe center. (C) 2014 Elsevier B.V. All rights reserved.

  The enantioselective synthesis of isochroman motifs has been accomplished via Pd(II)-catalyzed allylic C—H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide-oxazoline (ArSOX) ligand. The allylic C—H oxidation reaction proceeds with the broadest scope and highest levels asymmetric induction reported to date (avg. 92% ee, 13 examples ≥90% ee). Additionally, C(sp3)-N fragment coupling reaction between abundant terminal olefins and N-triflyl protected aliphatic and aromatic amines via Pd(II)/sulfoxide (SOX) catalyzed intermolecular allylic C—H amination is disclosed. A range of 52 allylic amines are furnished in good yields (avg. 76%) and excellent regio- and stereoselectivity (avg. >20:1 linear:branched, >20:1 E:Z). For the first time, a variety of singly activated aromatic and aliphatic nitrogen nucleophiles, including ones with stereochemical elements, can be used in fragment coupling stiochiometries for intermolecular C—H amination reactions.

  通过Pd(II)-催化的烯烃末端前体的烯丙基C—H氧化，已经实现了对异色烷基苯并环的对映选择性合成。这一目标的成功关键在于开发和利用一种新型手性芳基亚砜-噁唑啉（ArSOX）配体。烯丙基C—H氧化反应具有迄今报道的最广泛范围和最高水平的不对称诱导（平均92% ee，13个例子≥90% ee）。此外，通过Pd(II)/亚砜（SOX）催化的分子间烯丙基C—H胺化揭示了丰富的末端烯烃和N-三氟甲磺酰保护的脂肪族和芳香族胺之间的C(sp3)-N片段偶联反应。一系列52种烯丙基胺以良好的产率（平均76%）和优异的区域和立体选择性（平均>20:1线性:支链，>20:1 E:Z）提供。首次，各种单独活化的芳香族和脂肪族氮亲核试剂，包括具有立体化学元素的试剂，可以在分子间C—H胺化反应的片段偶联化学计量中使用。

  utilization of N‐centered radicals to synthesize nitrogen‐containing compounds has attracted considerable attention recently, due to their powerful reactivities and the concomitant construction of C−N bonds. However, the generation and control of N‐centered radicals remain particularly challenging. We report a tethering strategy using SOMO‐HOMO‐converted distonic radical anions for the site‐specific

  由于以N为中心的自由基具有强大的反应活性和随之而来的C-N键结构，因此利用N中心自由基合成含氮化合物已引起了广泛的关注。但是，以N为中心的自由基的产生和控制仍然特别具有挑战性。我们报告了在非共价相互作用的帮助下，使用SOMO-HOMO转化的二歧自由基阴离子进行亚胺和am定点胺化的束缚策略。该反应具有显着广泛的底物范围，并且还可以实现生物活性分子的后期功能化。此外，通过动力学研究，拉曼光谱，电子顺磁共振光谱和密度泛函理论计算，对反应机理进行了深入研究，

  The use of achiral N-acetyloxazolidine-2-thiones in the C-glycosylation of lactol acetates has allowed us to prepare with high diastereoselectivity the expected trans 2,5-disubstituted tetrahydrofurans. A study based on the role of the steric hindrance of the N-acetyloxazolidine-2-thiones is reported. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

  all: 4,5‐Spirocycles derived from 3‐oxetanone and β‐heteroatom‐substituted amino compounds undergo a Lewis acid mediated reaction cascade to form saturated nitrogen heterocycles. The unique reactivity of 3‐oxetanone facilitates access to biologically important morpholines, piperazines, and thiomorpholines with an otherwise difficult‐to‐access substitution pattern from readily available starting materials
