Abstract
Monocyclic 1,2,3-triazines were obtained by periodate oxidation of 1-aminopyrazoles in good reproducibilities and yields. The Diels-Alder reaction of 1,2,3-triazine with several enamines was carried out to afford 2,3-disubstituted pyridines. As an application of this method, we accomplished the synthesis of alkaloids, tortuosamine, N-formyltortuosamine and N-acetyltortuosamine
