N-Protected α-amino acids, prepared from benzoyl chlorides, KSCN and α-amino acids, were used as the acid component in the Passerini reaction, in an ionic liquid, to produce functionalized α-acyloxythioamides in 59-95% yields. The work-up procedure was fairly simple and the products did not require further purification.
