• Chemospecific Cyclizations of α‐Carbonyl Sulfoxonium Ylides on Aryls and Heteroaryls
  作者：Daniel Clare、Benjamin C. Dobson、Phillip A. Inglesby、Christophe Aïssa

  The functionalization of aryl and heteroaryls using α‐carbonyl sulfoxonium ylides without the help of a directing group has remained so far a neglected area, despite the advantageous safety profile of sulfoxonium ylides. Described herein are the cyclizations of α‐carbonyl sulfoxonium ylides onto benzenes, benzofurans and N‐p‐toluenesulfonyl indoles in the presence of a base in HFIP, whereas pyrroles

  尽管亚砜叶立德具有有利的安全性，但在没有导向基团帮助的情况下使用α-羰基亚砜叶立德对芳基和杂芳基进行官能化迄今为止仍然是一个被忽视的领域。本文描述了在 HFIP 中碱存在下，α-羰基亚锍叶立德在苯、苯并呋喃和 N-对甲苯磺酰吲哚上的环化，而吡咯和N-甲基吲哚在铱催化剂存在下进行环化。值得注意的是，这两组条件对于每组底物都是化学特异性的。
• Oxone–acetone mediated Wacker-type oxidation of benzo-fused olefins

  oxone–acetone combination for the Wacker-type oxidation of indenes and dihydronaphthalenes leading, respectively, to indan-2-ones and 2-tetralones. The amount of the base employed in the reaction seems to switch the reaction path from dioxygenation to Wacker-type oxidation. Control experiments suggest that the reaction is not proceeding via the epoxide route and also that there is no role of trace amounts

  在本文中，我们公开了将丙酮-丙酮组合物用于茚酮和二氢萘的瓦克型氧化反应的新应用，分别导致茚满-2-酮和2-四氢萘酮。反应中所用碱的量似乎将反应路径从双加氧转变为瓦克型氧化。对照实验表明，该反应不是通过环氧化物途径进行的，并且在当前的氧化反应中，试剂中不存在痕量金属也没有作用。

• Novel synthesis of phenol derivatives by palladium-catalyzed cyclocarbonylation of 2,4-pentadienyl acetates

  Phenyl acetates were selectively obtained in good yields by cyclocarbonylation of 2,4-pentadienyl acetates in the presence of NEt3, Ac2O, and a catalytic amount of palladium complexes such as PdCl2(PPh3)2 at 120-140-degrees-C under 50 atm of CO. No five-membered ring products were observed. A platinum complex PtCl2(PPh3)2 was also effective as a catalyst. The reaction of 5-phenyl-2,4-pentadienyl bromide with M(CO)(PPh3)3 (M = Pd or Pt) under CO gave the corresponding 6-phenyl-3, 5-hexadienoyl complexes in a high yield, which in turn afforded 2-acetoxybiphenyl in 41-51% yield on heating to 160-degrees-C under 50 atm of CO in the presence of NEt3 and Ac2O. Similar 3,5-hexadienoyl complexes are proposed to be intermediates in the catalytic cyclocarbonylation of 2,4-pentadienyl acetates. On the other hand, PdCl2(PPh3)2-catalyzed carbonylation of o-(bromomethyl)(1-alkenyl)-benzenes in the presence of NEt3 and Ac2O gave 2-naphthyl acetates in moderate yields, while the reaction in the absence of Ac2O gave five-membered ring products such as 2-indanones or a tricyclic lactone by incorporation of one or two CO molecules, respectively.
