Synthesis of carbon-14 analogue of 1,5 diaryl-5-[14C]-1,2,3-triazoles

2-Arylhydrazononitriles as building blocks in heterocyclic synthesis: A novel route to 2-substituted-1,2,3-triazoles and 1,2,3-triazolo[4,5-b]pyridines

“…[5] Plenty of 1,2,3-triazoles have also been reported to have useful pharmaceutical potential. [6-9] Synthetic approaches to 1,2,3-triazoloazines are rather limited. There are in fact few known routes to 4-functionally substituted 1,2,3-triazole-5-amines.…”

Preparation of four 1,4‐dihydropyridine derivatives (DHPs) labeled with carbon‐14

“…These compounds have been provided for further developments as novel antitubercular molecules that for the study of symmetric structure effect too. First, we obtained compound 1 with a single‐reaction; the reaction between labeled benzaldehyde, which has been previously described (Scheme ), with ethyl acetoacetate and ammonia was achieved with a relatively favorable yield (65%) as shown in Scheme . In the following, the labeled compound 1 was converted into 2 new DHP derivatives.…”

Hydrazononitriles as Precursors for 4‐aminotriazoles and 3‐aminoisoxazoles: One Pot Synthesis of triazolo[1,5‐a]quinazoline Derivatives

“…1,2,3‐triazoles have gained an extensive interest in view of their growing importance in agrochemical and medicinal fields . The importance of 1,2,3‐triazoles and their derivatives originates from their unique combination of facile accessibility via click chemistry and applications in supramolecular and coordination chemistry .…”
