coordinated to a palladium(II) cation in a bidentate fashion to construct a unique chiral environment at the palladium center due to the sterically demanding ferrocenyl groups. Ligand (R)-1 was applied in the palladium-catalyzed asymmetric synthesis of axially chiral allenes showing good enantioselectivity of up to 92% ee. In general, (R)-1 displayed better enantioselectivity than the parent Segphos in the

The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one‐pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23–90 °C) and providing complex polycyclic architectures with high efficiency, and atom and step economy. The bicyclo[2.2.2]octadiene products were obtained with

A series of A‐B type sterically regular bicyclio[3.3.0] diene‐based polymers were designed and synthesized as immobilized chiraldieneligands for asymmetric catalysis. With polymericdiene 6b, good to excellent enantioselectivities can be achieved in Rh‐catalyzed asymmetric 1,4‐addition of arylboronic acids to α,β‐unsaturated ketones.

Chiral 2-substituted-2-cyclohexen-1-one 2a is prepared. Conjugate additions of organometallic reagents to 2a occur with good to excellent diastereoselectivities. Enone 2b, which contains an additional potentially coordinating oxygen atom on the side chain of the chiral auxiliary, gave about the same stereoselectivity as 2a. The chiral auxiliary (S)-(+)-2-(methoxymethyl)pyrrolidine can be removed from

Flava Flavanone: Asymmetricconjugateadditions to chromones and 4‐quinolones are reported utilizing a single catalyst system formed in situ from Pd(OCOCF3)2 and (S)‐tBuPyOX. Notably, these reactions are performed in wet solvent under ambient atmosphere, and employ readily available arylboronicacids as the nucleophile, thus providing ready access to these asymmetric heterocycles (see scheme).
