N-benzyl derivative was investigated. In both series, stereoisomers at C-1, as well as regioisomer normal and neo compounds, were formed. Moreover, the N-unsubstituted products were partially lactamized, and the N-benzyl derivativesepimerized at C-1. In the products, the R configuration of C-1 over the S and the formation of the normal structure over the neo one predominated. The epimerization of both
