Abstract
AbstractBifunctional telechelics with defined structure can be prepared by oligomerization of oxiranes, β‐butyrolactone and L‐lactide using aluminium Schiff's base complexes as initiators. Chiral initiator (SALCENAlCl) shows a stereoelective character leading to preferential oligomerization of one enantiomer from a racemic monomer mixture. The reaction with β‐butyrolactone proceeds through O‐alkyl cleavage. Alkoxy Schiff's bases aluminium complexes are used for oligomerization of L‐lactide. All the prepared oligomers were fully characterized by IR, elemental analysis, 1H and 13C NMR and GPC.
