摘要：

Bifunctional telechelics with defined structure can be prepared by oligomerization of oxiranes, beta-butyrolactone and L-lactide using aluminium Schiffs 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 beta-butyrolactone proceeds through O-alkyl cleavage. Alkoxy Schiffs bases aluminium complexes are used for oligomerization of L-lactide. All the prepared oligomers were fully characterized by IR, elemental analysis, H-1 and C-13 NMR and GPC.
