Abstract: An efficient three-component domino reaction among oxa(aza)bicyclic alkenes, sodium azide, and primary haloalkanes is reported, which offers a mild access to 1,2,3-triazolines in an aqueous medium with excellent diastereoselectivities and yields. Further studies show that,… read more here.
