Js. Panek et B. Zhu, SYNTHESIS OF AROMATIC 1,2-DIAZINES BY INVERSE ELECTRON DEMAND DIELS-ALDER REACTION OF POLYMER-SUPPORTED 1,2,4,5-TETRAZINES, Tetrahedron letters, 37(45), 1996, pp. 8151-8154
Inverse electron demand Diels-Alder reactions of unsymmetrically subst
ituted 1,2,4,5-tetrazines immobilized on a solid support participate i
n thermally promoted cycloadditions with a wide range of electron-rich
dienophiles. The reactions afford functionalized 1,2-diazines bearing
a sulfur-based leaving group (-SR or -SO(2)R) at the C-6 position. Co
