摘要

Alkyl and aryl isothiocyanates react with oxalyl chloride (1) on both double bonds of the heterocumulene to yield 3-alkyl-or 3-aryl-2, 2-dichlorothiazolidine-4, 5-diones 2. The two chlorines in these novel orthocarbonic acid derivatives are readily exchanged by alkoxy groups to yield 2, 2-dialkoxythiazolidine-4, 5-diones 3; hydrolysis of
