Regio- and Stereoselective Ring Opening of Epoxides and Aziridines Using Zirconyl Chloride: An Efficient Approach for the Synthesis of β-Chlorohydrins and β-Chloroamines
Zirconyl chloride mediated regio- and stereoselective ring opening of epoxides and aziridines at room temperature affords the corresponding β-chlorohydrins and β-chloroamines, respectively in high yields.
