Reaction Steps
When the alkene-1,2-dicarboxylic acid compound starting material is an ester, such as diethyl fumarate, the addition of acetic anhydride and hydrogen sulfide proceeds to give the diethyl ester of S-acetylthiosuccinic acid, which on selective deacetylation, suitably by means of aqueous alcoholic ammonia, gives diethyl thiomalate according to this invention, as illustrated in SCHEME 2 below.
