摘要

3 transfer reagent 1 appears to be superior in many ways to the parent thiophosgene (2) or the 1, l'-thiocarbonyldiimidazole analogues (3). 2 For instance, reagent 1 reacts with primary amines in a selective fa~ hion,~ thus permitting the facile synthesis of unsymmetrically substituted thi0ureas. l This unexpected chemistry prompted us to explore its behavior as a dienophile. Parent thiophosgene (2) is well-known to react with various dienes to give ...
