A highly efficient one-pot synthesis of β,β-dihalo-β-nitroethyl alkyl ethers is achieved by the treatment of nitroalkenes with alcohols and N-halosuccinimides in the presence of sodium hydride. The notable advantages of this protocol are that it involves simple experimental manipulations and tolerates a wide range of functional groups. Further transformations of the obtained ethers, such as allylation
通过在氢化钠存在下用醇和N-卤代琥珀酰亚胺处理硝基烯烃,可以实现高效的一锅法合成β,β-二卤代-β-硝基乙基烷基醚。该协议的显着优点是它涉及简单的实验操作,并且可以耐受各种官能团。还研究了所得醚的进一步转化,例如烯丙基化和转化为β,β-二卤代乙烯基醚。
