efficient and green protocol for the synthesis of 2-oxazolines by the reaction of aromatic nitriles with β-aminoalcohols using sulfur under solvent-free conditions. The reaction occurs via the Willgerodt–Kindler mechanism followed by transamidation and dehydrosulfuration. This methodology offers several advantages such as good yields, mild and practical reactionconditions, simple work-up procedure, and

Transamidation of thioamides with 2-aminoethanol, followed by cyclodehydrosulfurisation of the resultant N-(beta-hydroxyethyl)thioamides, has been utilised for the mild and efficient synthesis of 2-oxazolines. The developed protocol was found to be of general applicability.
