One-Pot, Three-Component Cascade Synthesis of New Imidazoles by Van Leusen Reaction from 2-Functionally Substituted 2-Alkenals, Amines, and p-Tosylmethylisocyanide
The condensation of 2-alkylthiosubstituted 2-en-4-ynals with N , N - and N , O -binucleophiles gives the corresponding 1,3-perhydrodiazines, 1,3-imidazolidines, and 1,3-oxazolidines with an original combination of substituents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
