We report herein an unprecedented conjugate addition of enolizable ketones and unprotected mercaptoacetic acid to electron-poor alkenes using graphene oxide as a phase transfer catalyst. The envisaged protocol is versatile and applicable to structurally different Michael acceptors such as α,β-unsaturatedaldehyde/ketone/acid/ester/amide/nitrile, and β-nitroalkene to afford their corresponding adducts
