Abstract

Imidazol-1-yl-acetic acid is introduced as a new, efficient and recyclable green bifunctional organocatalyst for the synthesis of β-hydroxythiocyanate and 1,2-azido alcohols under mild conditions. This catalyst can be recovered by simple filtration and recycled up to 8 consecutive runs without losing any of its efficiency. Various advantages associated with this protocol include simple workup procedure, short reaction times, high product yields, greater regioselectivity.




Keywords: Imidazol-1-yl-acetic acid, epoxide, ring opening, bifunctional organocatalyst, sodium azide, sodium thiocyanate. green chemistry, nucleophile, electrophile, regioselective.
