  A Novel Photochromic System of 4,5-Dialkenylthiophenes Constructed by the Samarium Diiodide Promoted Coupling Reactions of Thiophene-2-carboxylate with Aryl Ketones

  摘要：

  [GRAPHICS]The Sml(2)-promoted coupling reaction of ethyl thiophene-2-carboxylate with aryl ketones (2 equiv), followed by acid-catalyzed dehydration and oxidative aromatization, gave dialkenylthlophenes 1b-d, which underwent electrocyclizations upon irradiation with 300-nm light in CH3CN solution to give the corresponding closed-ring species with absorption lambda(max) approximate to 425 nm. The interconversion between dialkenylthiophenes and their corresponding closed-ring species constitutes a novel photochromic system bearing an ester group for potential uses in linkage and wavelength tuning.

  Deprotection of 1,3-oxathiolanes to ketones promoted by base

  摘要：

  A variety of 1,3-oxathiolanes can be easily converted to the corresponding ketones in good yields with LTMP in THF. This deprotection methodology shows satisfactory chemoselectivity when other protecting groups, such as dimethylketal, 1,3-dioxolane, 1,3-dithiane, and other acid-sensitive groups, are present within the same substrates.

  intermediate tertiary carbocations. This approach has been implemented to achieve the first example of enantioselective reductive deoxygenation of tertiary alcohols. This reduction occurs with high enantio- (up to 96% ee) and regioselectivity (up to >50:1 rr) by applying a novel Hantzsch ester analogue as a convenient hydride source. In-depth mechanistic studies support the involvement of a tertiary carbocation

  引发对碳正离子的面部控制的固有困难限制了它们作为不对称催化中间体的效用。我们现在已经表明，涉及底物与手性过渡金属催化剂的可逆配位的对接策略可用于实现对中间叔碳正离子的高度立体选择性亲核攻击。这种方法已被实施以实现叔醇的对映选择性还原脱氧的第一个例子。通过应用新型 Hantzsch 酯类似物作为方便的氢化物来源，这种还原具有高对映性（高达 96% ee）和区域选择性（高达 >50:1 rr）。深入的机理研究支持通过关键的丙二烯部分与铱金属中心配位的叔碳正离子的参与。

  carbene–phosphine iridium complex system was found to be a very efficient catalyst for the methylation of ketone via a hydrogen transfer reaction. Mild conditions together with low catalyst loading (1 mol %) were used for a tandem process which involves the dehydrogenation of methanol, CC bond formation with a ketone, and hydrogenation of the new generated double bond by iridium hydride to give the

  N-杂环卡宾-膦铱络合物系统被发现是通过氢转移反应使酮甲基化的非常有效的催化剂。在串联过程中使用温和的条件，同时降低催化剂的负载量（1 mol％），该过程涉及甲醇的脱氢，与酮形成的CC键以及氢化铱将新生成的双键氢化以得到烷基化产物。使用这种铱催化剂体系，可以合成许多支链酮，转化率和收率都非常好。

  A metal‐catalyzed methylation process has been developed. By employing an air‐ and moisture‐stable manganese catalyst together with isotopically labeled methanol, a series of D‐, CD3‐, and 13C‐labeled products were obtained in good yields under mild reaction conditions with water as the only byproduct.

  A novel iminoxyl radical-promoted dichotomous regioselective 5-exo-trig cyclization onto vinylic halogen/1,2-halogen radical shift sequence is developed for the synthesis of halomethyl isoxazoles/cyclic nitrones using β-halo-β,γ- and γ-halo-γ,δ-unsaturated ketoximes as the substrates and PhI(OAc)2/TEMPO as the oxidation system. DFT calculations reveal that a halogen-bridged three-membered ring transition
