However, the cycloaddition of 3-(4',6'-dimethylpyrimidin-2'-yl)-phthalazinium-1-olate with ethyl acetylenecarboxylate was not regioselective and gave a mixture of two possible regioisomers.eninfo:eu-repo/semantics/closedAccessDipolar Cycloaddition ReactionsAryl-phthalaziniumArticle10410595598WOS:A1995TE51900004N/A
