Abstract

Chiral aluminum complexes 3 have been employed as catalysts for the stereoselective synthesis of cis-5-substituted 2-oxazoline-4-carboxylates from the aldol reaction of oxazole 1 and aldehydes. cis-Product diastereoselection ranges from 3:1–50:1, while enantioselectivities vary from 92–99 % for reactions with the 25 aromatic aldehydes investigated.
