Witryna4 lip 2024 · Copper-catalyzed 1,3-aminoazidation of arylcyclopropanes with N-fluorobenzenesulfonimide (NFSI) and trimethylsilyl azide (TMSN 3) has been established, facilely and efficiently affording a wide range of 1,3-diamine derivatives in moderate to good yields under mild conditions.It represents the first example of 1,3-diamination of … Witryna27 maj 2024 · In this work, a NBS-mediated 2,4-dibromohydration of enynes is described. It has been proved that ortho-acetamide participated in this 2,4-dibromohydration process. Mechanism studies show that an amide oxygen transfers into enynes to form a carbonyl of the products. One equivalent of water is incorporated in
