Abstract

Aryl and alkyl isoselenocyanates 2 react with ethyl γ-chloroacetoacetate (1) in the presence of triethylamine to give the corresponding 4-oxo-2-amino-4,5-dihydroselenophene-3-carboxylates 4a-f in moderate to good yields.

Keywords: Selenium heterocycles, isoselenocyanates, selenophenes, cyclization, βketoester, crystal structure
