Selective Synthesis of 5-Nitroindoles through a Ag-Catalyzed Nitro Rearrangement/Cyclization Cascade of N-(o-Alkynylphenyl)nitramines
{{output}}
The reactions of N-(o-alkynylphenyl)nitramines in the presence of catalytic amounts of AgNTf2 afforded 5-nitroindoles in good to acceptable yields in a site-selective manner. This cascade reaction is initiated by selective migration of the nitro group to the p... ...
