  Efficient and Regioselective Synthesis of 5-Hydroxy-2-isoxazolines: Versatile Synthons for Isoxazoles, β-Lactams, and γ-Amino Alcohols

  摘要：

  An efficient and highly regioselective protocol was developed for the preparation of 5-hydroxy-2-isoxazolines, which have been proved to be versatile synthons for isoxazles, beta-hydroxy oximes, and gamma-amino alcohols. beta-Lactams, commonly embedded in the skeletons of bioactive natural products, were also synthesized in two steps from beta-hydroxy oximes, providing a new strategy for the synthesis of this kind of compounds.
