Modification of chiral dimethyl tartrate through transesterification: Immobilization on POSS and enantioselectivity reversal in sharpless asymmetric epoxidation
Modification of dimethyltartrate has been investigated throughtransesterification with aminoalcohols to provide reactive functionalities for the covalent bonding of chiraltartrate to polyhedral oligomeric silsesquioxanes. The transesterification of dimethyltartrate has been widely studied using different catalytic systems and reaction conditions. Through the proper selection of both the catalytic
