Provided herein are compounds and pharmaceutical compositions of formula I where R1, R2, R3, R4, R5 and R6 are as described herein. Also provided pharmaceutically acceptable salts or stereoisomers of these compounds. In addition methods are provided for inhibiting the binding of an integrin to treat various pathophysiological conditions.
Highly c3-selective direct alkylation and arylation of 2-pyridones under visible-light-promoted photoredox catalysis

An Ir photoredox catalyst-mediated highly site-selective direct alkylation and arylation of 2-pyridones has been developed. Under visible-light-promoted conditions, ethyl 2-bromo-2,2-difluoroacetate couples with various 2-pyridones exclusively at the C3 position. A similar photoredox catalysis is also effective for the direct C3- Arylation with diaryliodonium triflates. Thus, these reactions occurs under very mild conditions (blue LEDs irradiation and ambient temperature) to form the corresponding C3- Alkylated and arylated 2-pyridones of potential interest in medicinal and pharmaceutical chemistry.
2-Pyridonate titanium complexes for chemoselectivity. accessing intramolecular hydroaminoalkylation over hydroamination
Chong, Eugene,Schafer, Laurel L.
supporting information, p. 6002 - 6005 (2014/01/06)
Chemoselectivity of intramolecular hydroaminoalkylation over hydroamination has been achieved with a bis(3-phenyl-2-pyridonate) titanium complex. Primary aminoalkenes are selectively α-alkylated by C-H functionalization adjacent to nitrogen to access five
