β¦ Synopsis
Dialkylaminium cation radicals pmduced from the title precursors add to ethyl vinyl ether to give &amino ethers in good yields. When an ally1 group is present on nitrogen, a cyclization reaction follows the addition, and pyrrolidines ate formed. Simple cyclic enol ethers also can be employed.
