摘要

Certain substituted 2-thiobarbituric acids have long been used as intravenous anesthetics 1 and as intermediates in the preparation of dyes. 10a More recently there has been interest in 2-thiobarbituric acids as anticonvulsants, 2., and immunotropic and anti-inflammatory compounds, 3 antineoplastic agents, 4 and as platforms in the synthesis of other biologically active compounds. 5., , and While deceptively simple in structure, 1,3-disubstituted-2- ...
