Abstract

Abstract An efficient, regioselective, one-pot and two-step synthesis of β-hydroxy 1, 4- disubstituted 1, 2, 3-triazoles from a wide range of non-activated terminal alkynes and epoxides and sodium azide by way of a three-component click reaction using a catalytic amount of [meso-tetrakis (o-chlorophenyl) porphyrinato] copper (II)(5 mol%) in excellent isolated yields is described. The reactions were performed in water as a green solvent at ...
