medicinal chemistry and organic synthesis is known. An efficient route to γ-keto sulfones through a metal-free reaction of cyclopropanols, sulfur dioxide and electron-deficient olefins is achieved. This reaction proceeds smoothly under mild conditions without the need of catalyst, oxidant or additive. A plausible mechanism is proposed, which undergoes through γ-keto sulfinate intermediate generated
The invention is an algorithm and method for designing an inhibitor that covalently binds a target polypeptide. The algorithm and method can be used to rapidly and efficiently convert reversible inhibitors into irreversible inhibitors.
The invention relates to protein conjugates that contain a protein kinase containing a cysteine residue in the ATP binding site and an inhibitor that is covalently and irreversibly bonded to said cysteine residue, such that the activity of the protein kinase is irreversibly inhibited. The invention also relates to compounds that irreversibly inhibit protein kinases.
A novel enantioselective protonation protocol that is triggered by reductive cross coupling of olefins is reported. When under cooperative photoredox and chiral hydrogen-bonding catalytic conditions and using a terminal reductant, various α-branched vinylketones with diverse vinylazaarenes could provide important enantioenriched azaarene derivatives containing tertiary stereocenters at their remote
