摘要：

A new approach to carbazoles and benzannulated carbazoles by means of intramolecular dehydro DielsAlder reactions of ynamides is reported. By using this approach, carbazoles and benzo[ b ]-, tetrahydrobenzo[ b ]-, naphtho[1,2- b ]-, naphtho[2,1- b ]-, and dibenzo[ a,c ]carbazoles have been prepared in moderate-to-good yields.
