Ultrasound-assisted rapid synthesis of [beta]-cyanoepoxides using hypervalent iodine reagents

An elegant approach for the rapid synthesis of [beta]-cyanoepoxides 3 by the epoxidation of [beta]-cyanostyrenes 1 with PIDA 2a is described. The epoxidation of [beta]-cyanostyrenes 1 was performed with 1.2 equiv. of PIDA 2a in MeCN-H2O (1:1) at room temperature in ultrasonic bath. The epoxidation r...

Description
Summary:An elegant approach for the rapid synthesis of [beta]-cyanoepoxides 3 by the epoxidation of [beta]-cyanostyrenes 1 with PIDA 2a is described. The epoxidation of [beta]-cyanostyrenes 1 was performed with 1.2 equiv. of PIDA 2a in MeCN-H2O (1:1) at room temperature in ultrasonic bath. The epoxidation reactions were completed in short reaction time and [beta]-cyanoepoxides 3 were isolated in 69-94% yields.
