Organoselenium-Induced Cyclization of Olefinic Imidates and Amides. Selective Synthesis of Lactams or Iminolactones
Lactams were formed selectively by the cyclization of olefinic imidates through the addition of a phenylseleno group to the double bond.Similar cyclization of olefinic amides, on the other hand, afforded either iminolactones or lactams depending on the st
