Saba, Shahrokh; Cagino, Kristen; Bennett, Caitlin – Journal of Chemical Education, 2015
A pedagogically useful discovery-based undergraduate organic chemistry lab experiment probing the chemo- and diastereoselectivity in the NaBH[subscript 4] reduction of two chiral ketoesters (benzoin acetate and benzoin benzoate) has been developed. This experiment complements a previously described and highly popular discovery-based experiment…

Saba, Shahrokh; Ciaccio, James A.; Espinal, Jennifer; Aman, Courtney E. – Journal of Chemical Education, 2007
The stereochemical investigation is conducted to give students the combined experience of chemical synthesis of amines and N-heterocycles and structural stereochemical analysis using NMR spectroscopy. Students are introduced to the concept of topicity-stereochemical relationships between ligands within a molecule by synthesizing N,O-acetals.
