Abstract

The preparations and structures of LAlOCH₂C(S)HMeCl, where L = (R,R) or (S,S)-N,N′-bis(3,5-di-tert-butyl-salicylidene)-1,2- cyclohexenediamino, are reported together with the respective LAlOEt compounds, and their reactivities toward L- and rac-lactides in various solvents reveal the surprising complexity of the stereopreference for the ring-opening event.
