InverseelectrondemandDiels-Alderreactions of unsymmetrically substituted 1,2,4,5-tetrazines immobilized on a solid support participate in 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 -SO2R) at the C-6 position.
