Synthesis and thermal behavior of a fused, tricyclic pyridine-based energetic material: 4-amino-5-nitro-[1,2,5]oxadiazolo[3,4-: e] tetra-zolo[1,5- a] pyridine-3-oxide

A fused, tricyclic pyridine-based energetic material, 4-amino-5-nitro-[1,2,5]oxadiazolo[3,4-e]tetrazolo[1,5-a]pyridine-3-oxide (ANTP), was first synthesized through a two-step reaction from commercially available reagents with a total yield of 75%, namely

Efficient synthesis of 4-amino-2,6-dichloropyridine and its derivatives

A facile synthetic route to an important intermediate 4-amino-2,6-dichloropyridine was developed. Oxidation of 2,6-dichloropyridine as a starting material gave pyridine N-oxide derivative which was subjected to nitration followed by reduction. Subsequent nitration of the product and nucleophilic displacement reaction were carried out to afford fully substituted energetic pyridine derivatives. Most of the synthetic reactions proceeded under mild conditions.
