Some of the products underwent TFA-catalyzed double bond isomerization and some did not. Cyclization reactions in the presence of alcohol catalyzed by Au(I) resulted in the formation of hemiacetals after cascade reactions.eninfo:eu-repo/semantics/openAccessAlkyne CyclizationGold-Catalyzed ReactionIndolo-Oxazin-1-OneMarine Natural ProductsPyrrolo-Oxazin-1-OneArticle11Q2Q289790526124892WOS:000355166500001
