, wherein L is a leaving group, and ring closure of the resulting urea. In this manner, certain 2-oxoimidazolidines may be manufactured that are useful intermediates for the production of Pramiconazole and structurally related compounds.
提供了一种制备式I的2-氧代咪唑啉的方法,包括以下一项或多项步骤:将胺转化为酰化剂,将酰化剂与结构为L-C(R4)(R5)—C(R2)(R3)—NHR1的双功能化合物缩合,其中L是一个离去基团,并闭环生成的脲。通过这种方式,可以制备出一些对于生产Pramiconazole和结构相关化合物有用的2-氧代咪唑啉中间体。
