Flava Flavanone : Asymmetric conjugate additions to chromones and 4‐quinolones are reported utilizing a single catalyst system formed in situ from Pd(OCOCF 3 ) 2 and ( S )‐ t BuPyOX. Notably, these reactions are performed in wet solvent under ambient atmosphere, and employ readily available arylboronic acids as the nucleophile, thus providing ready access to these asymmetric heterocycles (see scheme).
