Abstract The reaction of dithioethylketene, a new dithioalkylketene prepared in situ from dithio‐ethylacetyl chloride and triethylamine, with N,N ‐disubstituted 2‐aminomethylenecycloalkanones gave the 1,4‐cycloadducts, namely N,N ‐disubstituted 4‐amino‐3,4‐dihydro‐3,3‐dithioethyl‐5,6‐polymethylene‐α‐pyrones.
