Expeditious Formation of 1,2,4-Triazine Derivatives via a Thioisomuenchnone Cycloaddition Reaction
Article
  • Dec 1999
  • TETRAHEDRON LETT
A novel type of heterocyclization reaction involving the [3+2] cycloaddition of N,N-dialkylamino-substituted thioisomünchnones with azodicarboxylates gives rise to 1,2,4-triazine derivatives after a selective fragmentation pathway of the transient cycloadducts. The X-ray analysis of 7 accounts for the fate of this particular transformation. An asymmetric version using chiral carbohydrate-based thioisomünchnones has also been disclosed.
