Stereoselective synthesis of a candoxatril intermediate asymmetric hydrogenation
摘要:
A four step synthesis of a chiral glutarate half ester intermediate, required for the preparation of candoxatril, has been developed from t-butyl acrylate. The key steps in this route include a stereoselective synthesis of a trisubstituted alkene and its asymmetric hydrogenation with a Ru-BINAP catalyst. (C) 1999 Elsevier Science Ltd.
