Cyclization of propargylic amide

Base-catalyzed cyclization of propargyl amides is an expeditious approach to a variety of substituted oxazoles. In addition, propargyl amides can serve as... [Pg.51]

Zinc The 5-exo-dig cyclization of propargylic amide (210), mediated by Znl2, has been reported to produce the exo-methylene oxazoline (211). With = H and FeC as the reagent, oxazole (212) was obtained as a result of the final aromatization. ... [Pg.368]

The Fe -mediated cyclization of propargylic amides (210) to produce oxazoles (212) was discussed in connection with Zn -mediated reactions (vide supra)P ... [Pg.369]
