Herein, we have explored the enantioselective Michael addition of various malonate esters to benzalacetophenone by successful utilization of chiral phase transfer catalysts derived from proline, mandelic acid and tartaric acid under mild phase transfer conditions. The obtained results signify that these chiral phase transfer catalysts are efficacious towards enantioselective Michael addition as the use of it resulted in good enantioselectivity and appreciable chemical yields.Graphic AbstractSYNOPSIS Highly enantioselective Michael addition of dialkyl malonates to benzalacetophenone has been established under mild phase transfer conditions, by successful utilization of chiral phase transfer catalysts derived from proline, mandelic acid and tartaric acid (I-VI) with appreciable chemical yields.
