  摘要：

  A new approach toward the synthesis of 3-alpha-hydroxyalkyl-5,6-dihydro-4H-1,2-oxazines 1 from available 5,6-dihydro-4H-1,2-oxazine N-oxides 2 has been described. The key step of the process-the rearrangement of 3-alkiliden-2-siloxy-tetrahydro-1,2-oxazines 3 (ASENA)-was thoroughly investigated. Optimal experimental conditions were developed. A possible pathway of the ASENA rearrangement was proposed. (C) 2009 Elsevier Ltd. All rights reserved.

  The nucleophile-induced rearrangement of cyclic N-alkoxy-N-(silyloxy)enamines was investigated. As a result, a new strategy for the synthesis of β-pyranone and β-furanone derivatives from nitro compounds is suggested. nitroso acetals - rearrangement - nitrogen heterocycles - 1,2-oxazines - aliphatic nitro compounds

  alkyl, and ester) at the C3 and C4 positions of the resulting isoxazolines were also tolerated. A quick assembly of the isoxazoline ring starting from nitroalkenes and malonates was successfully developed. Control experiments showed that the intramolecular ring closure is the most likely key mechanistic step. Subsequent transformations into pyrrolidine and furane derivatives demonstrated the synthetic

  A new tandem double acylation/rearrangement reaction of nitro compounds is described. It has a broad substrate scope allowing the mild and efficient synthesis of α-acyloxy oxime esters in high yields and regioselectivity. According to the obtained data, the mechanism for transformation was proposed. The utility of the obtained α-hydroxy oxime esters was demonstrated.
