Convenient procedures for the chemo-and diastereoselective reduction of p-enamino esters 1 are described. Both cis-and trans-y-amino alcohols 2 or p-amino esters 3 can be prepared by reduction of p-enamino esters 1, readily available starting materials, with the use of inexpensive reagents Ndi-PrOH or NaHB (OAc) dAcOH, respectively, and the appropriate reduction conditions. The mechanisms and diastereoselectivities for the reductions are ...
