Efficient pyrrolidine catalyzed cycloaddition of aziridines with isothiocyanates, isoselenocyanates and carbon disulfide "on water"
The cycloaddition of aziridines with isothiocyanates, isoselenocyanates and carbon disulfide has been described using pyrrolidine as catalyst on water at moderate temperature. This protocol features the use of commercial amine as catalyst and water as sol
"On water": Efficient iron-catalyzed cycloaddition of aziridines with heterocumulenes
In suspension: The reaction of aziridines with heterocumulenes in the presence of Fe(NO3)3×9 H2O in aqueous suspension provides access to functionalized five-membered heterocycles in good to high yields. This protocol has a wide substrate scope, is simple, and uses a nontoxic and cheap catalyst. Copyright
