agrochemicals and therapeutics. This structural motif is of interest in the synthesis of small building blocks suitable for the preparation of potentially bioactive molecules. In this sense, 5‐alkylidene and 5‐arylidenehydantoins constitute nice examples of precursors of synthetic α‐amino acids. The microwave‐assisted synthesis of these compounds under green chemistry conditions is reported in this article
摘要 乙内酰
脲已成为一类众所周知的结构,在农用
化学品和治疗剂方面有着重要的应用。这种结构基序在合成适合制备潜在
生物活性分子的小构件中很重要。从这个意义上说,5-亚烷基和5-亚芳基乙内酰
脲构成合成
α-氨基酸前体的很好例子。本文报道了这些化合物在绿色
化学条件下的微波辅助合成。该方法已证明可提供 74-96% 的产率。
