An efficient asymmetric synthesis of the four stereoisomers of 3-hydroxyleucine
摘要:
The four stereoisomers of 3-hydroxyleucine have been prepared in high overall yield and enantiomeric purity. Key steps include Sharpless asymmetric epoxidation, benzyl isocyanate-induced epoxide opening, and epimerization of an intermediate oxazolidinone ester.
