摘要

The aza-annulation of enamino ester substrates has been demonstrated as an efficient alternative to the syntheses of non-benzodiazepine sleep inducers. Enamino ester substrates derived from aryl, thiophene, and indole functionality were prepared from the corresponding ethyl amines by isothiocyanate formation followed by acid catalyzed cyclization.
