  Dynamic kinetic resolution of (S)-mandelate-derived α-bromo esters in nucleophilic substitution reaction has been investigated. Substitutions with various alkyl amine nucleophiles in the presence of TBAI and DIEA can provide various α-amino esters up to 81% yield and 97:3 dr. Also, the substitution of α-bromo esters with N-substituted 2-aminoethanol nucleophiles and following spontaneous cyclization

  已经研究了 (S)-扁桃酸衍生的 α-溴酯在亲核取代反应中的动态动力学拆分。在 TBAI 和 DIEA 存在下用各种烷基胺亲核试剂取代可以提供各种 α-氨基酯，产率高达 81% 和 97:3 dr。此外，用 N-取代的 2-氨基乙醇亲核试剂取代 α-溴酯并随后自发环化为高达 95:5 er 的 3-取代吗啉-2-酮的不对称合成提供了实用的方案。

• A facile route for highly enantioenriched six‐membered 1,4‐<i>N,N</i>‐ and <i>N,O</i>‐heterocycles from <scp>L</scp>‐serinate‐derived <scp>α</scp>‐bromoacetates

  Preparation of highly enantioenriched six-membered 1,4-N,N- and N,O-heterocycles has been developed through [4 + 2] heteroannulation of α-bromoacetates with 1,4-binucleophiles. Two consecutive substitutions of highly diastereoenriched L-serinate-derived α-bromoacetates provide convenient access to a wide range of C-aryl/aliphatic substituted 1,4-N,N- and N,O-heterocycles with up to 99:1 er.
