The stereochemistry of the various conversions in the 1,2-diphenyl-1-propyl system was measured as a function of aromatic substituent. For β-anisyl groups the reaction occurred with retention of configuration. For compounds with indifferent electron donating aryl groups, the conversions were stereoselective forming mostly threo product. For β-p-nitrophenyl groups the stereochemical course of the reaction
