Copper-promoted iodovinylation of amides: synthesis of β-functionalized enamides
摘要:
We studied the addition of nitrogen radicals to ynol ethers in order to form beta-functionalized enamides. Poor yields are reported. On the other hand, we observed that copper coupling between 1,2-diiodoethene and various amides leads to beta-functionalized enamides in high yields with complete stereocontrol.
