  Catalytic Asymmetric Cycloadditions of Silyl Nitronates Bearing α-Aryl Group

  摘要：

  1,3-Dipolar cycloadditions of 2-alkylacroleins or atropaldehyde with triisopropylsilyl nitronates bearing an alpha-ary] group produced 3-aryl-2-isoxazolines having a chiral quaternary center in up to 94% ee and up to 88% yield with the aid of Corey's oxazaborolidine catalyst. Specifically, the TIPS nitronate with an alpha-(p-methoxyphenyl) group gave mainly the 2-isoxazolines having an all-carbon quaternary center.

• Manganese-Promoted Oxidative Cyclization of Unsaturated Oximes Using Molecular Oxygen in Air under Ambient Conditions

  A highly efficient manganese-promoted oxidative cyclization of unsaturated oximes to afford the corresponding 4,5-dihydroisoxazoline alcohols was developed. A very low loading (generally 0.1–0.2 mol-%) of Mn(acac)3 (acac = acetylacetonate) promoted the oxidative cyclization through the direct incorporation of molecular oxygen present in air (open flask) at room temperature.

  开发了一种高效的锰促进的不饱和肟氧化环化，以提供相应的 4,5-二氢异恶唑啉醇。Mn(acac)3（acac = 乙酰丙酮化物）的负载非常低（通常为 0.1–0.2 mol-%）通过在室温下直接掺入空气（开口烧瓶）中存在的分子氧来促进氧化环化。

  This paper describes a palladium-catalyzed oxime assisted intramolecular dioxygenation of alkenes by using 1 atm of air as the sole oxidant under extremely mild conditions, which demonstrated the feasibility of incorporating atmospheric oxygen into synthetically useful products under 1 atm of air at room temperature.
