A Convenient Practical Method for the Preparation of (-)-(1S,2S)-5-Norbornene-2-carboxylic Acid, Incorporating Efficient Recovery of the Chiral Auxiliary D-Pantola
文摘
A convenient practical method was developed for the preparation of enantiomerically pure (-)-(1S,2S)-5-norbornene-2-carboxylic acid, wherein the chiral auxiliary D-pantolactone wasrecovered efficiently.
