TL;DR: The synthesized bis(guanidinate) alkoxides are able to promote the stereoselective ROP of rac-beta-butyrolactone to afford syndiotactic poly(hydrobutyrate) through a chain-end control mechanism, while they are surprisingly non-stereoselectIVE for the Rop of lactide under strictly similar conditions.
