| Abstract: | reaction: see text]. A new approach to carbazoles and benzannulated carbazoles by means of intramolecular dehydro Diels-Alder reactions of ynamides is reported. By using this approach, carbazoles and benzob]-, tetrahydrobenzob]-, naphtho1,2-b]-, naphtho2,1-b]-, and dibenzoa,c]carbazoles have been prepared in moderate-to-good yields. |
