A method for the preparation of novel oxaza and diaza polycyclic 9-oxa-4-azaphenanthrene, 5H-pyrido[2,3-α]pyrrolizine, 5H,6H-pyrido[3,2-g]indolizine, and 5H,6H-indeno[2,1-α]indole is described, based on tandem reactions: aza-Wittig reaction of N-vinylic phosphazenes with functionalized aldehydes and an intramolecular aza-Diels - Alder reaction.
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
