A practical synthesis of enantiopure substituted 3-hydroxy-pyrrolidines is reported. In four steps, starting from commercially available amino acids as chiral educts, this method allows for an efficient preparation of a variety of 3-hydroxy-pyrrolidines, as well as 3-hydroxy-piperidines and azepanes. Application of this methodology for a straightforward asymmetric synthesis of (−)-bulgecinine is also
报道了对映体纯的取代的3-羟基-吡咯烷的实际合成。从市售氨基酸作为手性离析物开始,在四个步骤中,该方法可有效制备各种3-羟基-吡咯烷,3-羟基-哌啶和氮杂环庚烷。还介绍了该方法在(-)-bulgecinine的直接不对称合成中的应用。
