The identification of a series of sulfonyl-amino-acetamides as BACE-1 (β-secretase) inhibitors for the treatment of Alzheimer’sdisease is reported. The derivatives were designed based on the docking simulation study, synthesized and assessed for BACE-1 inhibition in vitro. The designed ligands revealed desired binding interactions with the catalytic aspartate dyad and occupance of S1 and S2′ active
Ynamides are versatile buildingblocks in organic synthesis. However, the synthesis of amino acid-derived ynamides is difficult but in high demand. Herein, we disclose the copper-catalyzed Csp-N coupling of sulfonamide, including amino acid and peptidederivatives, to give ynamides by using alkynyl benziodoxolones with broad functional group tolerance under mild reaction conditions. The electron-rich
A palladium-catalyzed aerobic intermolecular 1,2-diamination of conjugateddienes has been developed using ethanediamine and α-amino amide derivatives as nitrogen sources respectively. A variety of valuable substituted piperazines and 2-piperazinones were synthesized in good yields and with high regio- and chemoselectivity.
