Synthesis of Unsymmetrical Annulated 2,2’-Bipyridine Analogues with Attached Cycloalkene and Piperidine Rings via Sequential Diels-Alder Reaction of 5,5’-bi-1,2,4-triazines(†)
Synthesis of bisfunctionalized unsymmetrical 2,2’-bipyridines 8 or their sulfonyl derivatives 12a,b are described. They were prepared via the Diels-Alder reaction of 1‑methyl-4-pyrrolidin-1-yl-1,2,3,6-tetrahydropyridine (6) with 3,3’-bis(methyl-sulfanyl)-5,5’-bi-1,2,4-triazine (1). The reaction lead...
