Benzimidazole derivatives of Formula I, that modulate the activity of ACSS2 are disclosed for therapeutic use. The fused imidazole ring of the compounds disclosed has a diarylmethyl or diarylmethanol moiety attached at the 2-position and the compounds have at least one other substituent at the 5 or 6 position of the benzimidazole. Also disclosed are methods of using the benzimidazole compounds for the treatment of diseases or disorders, such as cancer.

room-temperature, regioselective Minisci reaction for the acylation of electron-deficient heteroarenes with alkynes. The method has broad functional group compatibility and gives exclusively monoacylated products in good to excellent yields. The mechanistic pathway was analyzed based on a series of experiments confirming the involvement of a radical pathway. The 18O-labeling experiment suggested that water

A flow microreactor method for the synthesis of disubstituted pyridines by generation of pyridyllithiums followed by reactions with electrophiles has been developed. By using a short residence time and efficient temperature control, the cryogenic conditions required for conventional batch macro processes can be avoided. Sequential introduction of two different electrophiles into dibromopyridines has

Highly Enantioselective Hydrogenation of Non-<i>ortho</i>-Substituted 2-Pyridyl Aryl Ketones via Iridium-<i>f</i>-Diaphos Catalysis
This work disclosed a highly enantioselective hydrogenation of non-ortho-substituted 2-pyridyl arylketones via Ir/f-diaphos catalysis. This catalytic system allows for full control over the configuration of the stereocenter, affording two enantiomers of the desired products with extremely high enantioselectivity (up to >99% ee in most cases) and excellent reactivity (TON of up to 19600, TOF of 1633
