stable, nonhygroscopic, and readily available chiral derivatizing agent (CDA) for NMRchiral discrimination of chalcogen containing secondary alcohols. The chiralrecognition by CDA and chiralsolvatingagent (CSA) was assessed using 1H, 77Se‐1H}, and 125Te‐1H} NMRspectroscopy. A simple model for the assignment of the absolute configuration from NMR data is presented.
