From five to two: The addition of deprotonated Strecker products to N‐acylimines permits the synthesis of tetrasubstituted imidazoles or trisubstituted oxazoles in three or four steps, respectively. In total, the target compounds are prepared from two aldehydes, a primary amine, an acid chloride and ammonia (see scheme).
