A convenient route for the synthesis of a variety of salan-type compounds is introduced. The synthesis is based on a single-step Mannichcondensation between readily available starting materials: primary or secondary amines, formaldehyde and substituted phenols. This methodology is suitable for the preparation of chiral salans as well, which may find applications in asymmetric catalysis.

By combining the influence of excess alcohol, temperature and monomer-to-initiator ratios in the feed, dinuclear salan aluminum complexes LRAl2Me4 exhibited a high degree of control towards the copolymerization of L-LA and ε-CL, producing blocky, gradient, tapered and random copolymers.
