[reaction: see text] An efficient and clean synthesis of N-aryl azacycloalkanes from alkyl dihalides and aniline derivatives has been achieved using microwave irradiation in an aqueous potassium carbonate medium. The phase separation can simplify the product isolation and reduce usage of volatile organic solvents.
Abstract A ruthenium based catalytic system ([Ru(p-cymene)Cl2]2/XantPhos with substoichiometric Cs2CO3) has been established to effectively achieve the first direct amination cyclization of 1,2,4-butanetriol with primary aromatic amines. The product of this sustainable hydrogen autotransfer process is valuable N-aryl-3-pyrrolidinol.
