  Stereoselective Cyclization Reactions of IBX-Generated Alkoxyamidyl Radicals

  摘要：

  [GRAPHICS]In this paper, a method for the generation of alkoxyamidyl radicals is presented. These N-centered radicals can efficiently be formed starting from the corresponding acylated alkoxyamines using IBX as an oxidant. Stereoselective 5-exo and 6-exo reactions with these N-heteroatom-centered radicals leading to isoxazolidines and [1,2]oxazinanes are discussed. The N-O bond in the heterocycles can readily be cleaved with SmI2 to provide N-acylated 1,3-amino alcohols.

  heterocycle aza‐oxonium ylides through intramolecular and intermolecular cycloadditions with alkenes. This allowed a systematic study of the reactivity of the transient aza‐oxonium ylide intermediate, which can undergo N−O bond cleavage followed by nitrene C−H insertion, and the formation of β‐lactams or isoxazolidinones upon varying the structure of the alkene or O‐isocyanate reagents.

  1,3-偶极子通常用于[3 + 2]环加成反应，而等电不带电偶极子变体仍未开发。与传统的1,3-偶极子相反，不带电荷的偶极子等价物形成两性离子环加合物，可用于构建进一步的分子复杂性。在这项工作中，氧取代的异氰酸酯的第一个环加成反应（O-异氰酸酯）通过实验和DFT计算进行了研究。通过与烯烃的分子内和分子间环加成反应，这种独特的环加成反应策略可提供一类新型的杂环氮杂-氧鎓叶立德。这使得可以对瞬态氮杂-氧鎓叶立德中间体的反应性进行系统的研究，该中间体可以经历N-O键裂解，然后插入亚硝基CH并通过改变烯烃或烯烃的结构形成β-内酰胺或异恶唑烷酮。O-异氰酸酯试剂。

  Iminium ions generated from isoxazolidines and tetrahydro-1,2-oxazines undergo allylation under Sakurai conditions. Allylated isoxazolidines are formed predominantly as the trans isomer, while oxazines are formed exclusively as the cis isomer.

  Treatment of O-homoallylhydroxylamines with palladium(II) and copper(II) in the presence of a base, methanol, and carbon monoxide results in the formation of isooxazolidines. An electron-withdrawing group on the hydroxylamine nitrogen is essential. When carbamate groups are used the products are formed exclusively as their cis isomers.
