Abstract
Abstract A synthesis of chiral flavanones via the condensation of tricarbonyl (h6- arylbenzaldehyde) chromium (0) and o-hydroxyacetophenone in a shorter time at room temperature have been developed. The tricarbonylchromium (0) group was removed by virtue of light and the enantioenriched flavanones was formed with highly enantioselectivity (> 95% ee).
