Inverse electron demand diels-alder reactions of 1,2,3-triazines: Pronounced substituent effects on reactivity and cycloaddition scope

supporting information; experimental part, p. 12285 - 12292 (2011/09/16)
A systematic study of the inverse electron demand Diels-Alder reactions of 1,2,3-triazines is disclosed, including an examination of the impact of a C5 substituent. Such substituents were found to exhibit a remarkable impact on the cycloaddition reactivity of the 1,2,3-triazine without altering, and perhaps even enhancing, the intrinsic cycloaddition regioselectivity. The study revealed not only that the reactivity may be predictably modulated by a C5 substituent (R = CO2Me > Ph > H) but also that the impact is of a magnitude to convert 1,2,3-triazine (1) and its modest cycloaddition scope into a heterocyclic azadiene system with a reaction scope that portends extensive synthetic utility, expanding the range of participating dienophiles. Significantly, the studies define a now powerful additional heterocyclic azadiene, complementary to the isomeric 1,2,4-triazines and 1,3,5-triazines, capable of dependable participation in inverse electron demand Diels-Alder reactions, extending the number of complementary heterocyclic ring systems accessible with implementation of the methodology.

, p. 517 - 520 (2007/10/03)
A number of 4′-heterocyclic biphenylsulfonamide derivatives, formally derived from BMS-193884 (1) by replacing the oxazole ring with other heterocyclic rings, are potent and selective endothelin A (ETA) receptor antagonists. Among the analogues examined, the pyrimidine derivative 18 is the most potent (Ki=0.9 nM) and selective for the ETA receptor, approximately equivalent to 1.
