Taylor, Edward C.,French, Larry G.
, p. 1245 - 1249 (2007/10/02)
A synthetic route to benzopyranopyrazines and the first reported synthesis of the pyrazinoquinoline system are described whereby the fused pyrazine ring is constructed by an intramolecular nitrile/1,2,4-triazine Diels-Alder cycloaddition.Uns
INTRAMOLECULAR DIELS-ALDER REACTIONS OF 1,2,4-TRIAZINES: SYNTHESIS OF TRICYCLIC CONDENSED PYRIDINES AND PYRAZINES
Taylor, Edward C.,French, Larry G.
, p. 1967 - 1970 (2007/10/02)
Syntheses of several 6,6,6-tricyclic condensed pyridines and pyrazines utilizing intramolecular Diels-Alder reactions of 1,2,4-triazines with alkyne and nitrile dienophiles are detailed.The cyclisations are facilitated by the presence of conformationally
