Direct Phosphonation of Quinolinones and Coumarins Driven by the Photochemical Activity of Substrates and Products
Light-promoted phosphonation of quinolinones
and coumarins was
developed without the need for an external photocatalyst. Investigations
support a mechanism whereby both starting materials and products act
as photosensitizers upon excitation using compact fluorescent light
sources to photochemically promote the dissociation of the N–O
bond in the pyridinium salt by a single electron transfer pathway.
A wide range of quinolinone and coumarin substrates can be utilized
in the phosphonation process under mild reaction conditions
Ru(II)-Catalyzed Site-Selective Hydroxylation of Flavone and Chromone Derivatives: The Importance of the 5‑Hydroxyl Motif for the Inhibition of Aurora Kinases
An
efficient protocol for RuÂ(II)-catalyzed direct C–H oxygenation
of a broad range of flavone and chromone substrates was developed.
This convenient and powerful synthetic tool allows for the rapid installation
of the hydroxyl group into the flavone, chromone, and other related
scaffolds and opens the way for analog synthesis of highly potent
Aurora kinase inhibitors. The molecular docking simulations indicate
that the formation of bidentate H-bonding patterns in the hinge regions
between the 5-hydroxyflavonoids and Ala213 was the significant binding
force, which is consistent with experimental and computational findings
