Direct amination of olefins through sequential triazolinedione ene reaction and carbanion-assisted cleavage of the N-N urazole bond
(formula presented) Allylic amines 5 are obtained in 30-55% overall yields by the base-catalyzed hydrolysis of trialkylated allylic urazoles 3; the latter are prepared by the TAD ene reaction of the appropriate olefin and further N-alkylation with α-bromo
