Solid-phase synthesis of 1,2,4-triazolidine-3,5-diones
摘要:
A traceless synthesis of 1.2.4-triazolidine-3.5-diones has been achieved through cyclo-elimination from solid-phase. This traceless cyclo-elimination release step is induced by catalytic amount of base or by simply refluxing the urea carbamate intermediate. (C) 2002 Elsevier Science Ltd. All rights reserved.
