Dialkylaminium cation radicals produced from the title precursors add to ethyl vinyl ether to give β-amino ethers in good yields. When an allyl group is present on nitrogen, a cyclization reaction follows the addition, and pyrrolidines are formed. Simple cyclic enol ethers also can be employed.
由标题前体产生的二烷基铵阳离子自由基加到乙基乙烯基醚上,以良好的收率得到β-氨基醚。当在氮上存在烯丙基时,加成之后进行环化反应,并形成吡咯烷。也可以使用简单的环状烯醇醚。
