scheme or table, p. 5773 - 5776 (2009/12/26)
The synthesis of all four regioisomers of fused pyrrolidino-pyridines in a one-pot two-step sequential Ugi-inverse electron demand Diels-Alder reaction is described. Fused pyrrolidino-pyrazines, pyrrolidino-pyrimidines and azepinone pyridines can also be obtained in consecutive synthetic sequences.
Novel 6-azapteridines from bifunctional 1,2,4-triazines
Wamhoff, Heinrich,Tzanova, Milena
, p. 965 - 974 (2007/10/03)
The convergent synthesis of ethyl 5-chloro- and 5-amino-3-aryl-1,2,4-triazinecarboxylates 9a-9d and 10a-10d as well as of 5-amino-3-aryl-1,2,4-triazine-6-carboxamides 11a-11d is described. Compounds 9, 10 and 11 are powerful key compounds for cyclization reactions to the novel pyrimido[4,5-e][1,2,4]triazines 13d, 14c, 14d, 15c and 17a, 17d.
