A novel lactam synthesis fromalkyne having amide in a tether was developed. The reaction proceeds via a vinylketene complex generated fromalkyne and Fischer chromium carbene complex, and the lactam ring was formed from carbon monoxide, alkyne carbon and nitrogen of tosylamide. The four-,five-, six-, and seven-membered lactams having a substituent at the α-position were obtained in good yields.
