Enamines, as dienophiles

Some highly substituted carbazoles were obtained by photo-induced Diels-Alder reactions of 2-(l-cyano-vinyl)indoles using stabilized enamines as dienophiles. <94SL141>... [Pg.122]

Pyrrolidine has been the common organocatalyst used by Boger and coworkers for the synthesis of highly substituted pyridines based on the inverse-electron-demand Diels-Alder reaction of in situ formed enamines and 1,2,4-triazines. Barbas and coworkers have described the amine-catalysed direct self-Diels-Alder reaction of a,p-unsaturated ketones. The inverse-electron-demand hetero-Diels-Alder reaction of nitrosoalkenes and in situ formed enamines as dienophiles was also shown to be possible. ... [Pg.13]
