Transition-metal-free multinitrogenation of amides by C-C bond cleavage: A new approach to tetrazoles

A metal-free brand-new one-pot multinitrogenation of amides for the chemo- A nd regioselective synthesis of 1,5-disubstituted tetrazoles has been developed. By means of electrophilic amide activation, and further C-C bond cleavage and rearrangement, a diverse set of functionalized 1,5-DST derivatives were selectively constructed under mild conditions. As showcased in the mechanisms, the chemoselectivity is easily switched by the selection of the starting materials in the reaction.

Improved Schmidt synthesis of 1,5-disubstituted 1H-tetrazoles from ketones

On treatment with an excess of sodium azide in the presence of titanium(IV) chloride in boiling acetonitrile, both aliphatic and aromatic ketones are smoothly converted to 1,5-disubstituted 1H-tetrazoles in high yields.
