Abstract: Herein, we describe a catalytic asymmetric intramolecular vinylogous aldol reaction by taking advantage of dual organocatalysts, which enables convergent synthesis of ortho-fused tricyclic diketones in excellent enantioselectivities and diastereoselectivities. Noteworthy is that the reaction stereoselectively… read more here.

Abstract: Aromatic ring fusion to porphyrins and their derivatives represents an attractive route to tune the molecular conjugation and thus expand their functionalities. Here, we report the expansion of the aromatic π-system of palladium tetraphenyltetrabenzoporphyrins (Pd-TPTBP)… read more here.
