and compounds comprising a halogen atom having a formal oxidation state of 1+, 3+, 5+ or 7+, provided that the electrophilic oxidating agent is not iodobenzene diacetate. The process can be conveniently employed in the synthesis of 1,3-amino alcohols, β-amino acids and heterocyclic compounds, in particular β-amino acids.
本发明涉及一种保护胺化合物去保护的方法,其中所述保护胺化合物与一种选自I2、Br2、Cl2和含有形式氧化态为1+、3+、5+或7+的卤素原子的化合物的亲电氧化剂接触,所述亲电氧化剂可以在现场形成,但所述亲电氧化剂不是碘苯二乙酸酯。该方法可方便地应用于1,3-氨基醇、β-氨基酸和杂环化合物的合成,特别是β-氨基酸的合成。
