��� Some unsuccessful attempts to convert 4-acylamino-1,2-dithiole derivatives into pyrrolodithioles are described, and the failure of the critical cyclization step is discussed. The reaction of 4-acetoacetamido-1,2-dithiol-3-one with sodium ethoxide has given 5-carbethoxy-2,3-dihydro-4H-1,4-thiazin-3-one (XI).
