Propargyl amide cycloisomerization

Propargylic amides 56 are converted to oxazoles of type 58 by Au(III)-catalyzed cycloisomerization via (spectroscopically detectable) 5-methylene-4,5-dihydrooxazoles 57 [268] ... [Pg.174]

In addition to the enyne cycloisomerization, the reactivity patterns of propargylic esters were investigated intensively [57], which were based on early work of Uemura for other metals [58, 59]. Thus, we chose propargylic amides as substrates. [Pg.149]
