Web[4+2] cycloadditions of tetrazine 1 (Tz) and rhenium-coordinated tetrazine 5 (Re-Tz) with styrene (2, St) leads to the formation of intermediates 3 and 6, respectively. This is followed by a retro-[4+2] cycloaddition to form dihydropyridazines 4 and 7. The regioisomers in which the Ph group is ortho to the pyridyl sub-stituent are shown. WebHigher blocking capacity is correlated with better in vivo performance of the respective Tz. 14 As expected – based on our previous data – we found a correlation between clog D 7.4 and in vivo blocking of the Tzs tested in the assay (Pearson's r = 0.89, p <0.01) and the most polar Tz 21 (clog D 7.4 = −6.93) resulting in the best blocking ...
