Fast and Efficient Postsynthetic DNA Labeling in Cells by Means of Strain-Promoted Sydnone-Alkyne Cycloadditions

Sydnones are highly stable mesoionic 1,3-dipoles that react with cyclooctynes through strain-promoted sydnone-alkyne cycloaddition (SPSAC). Although sydnones have been shown to be valuable bioorthogonal chemical reporters for the labeling of proteins and

SYDNONE DERIVATIVES FOR CONJUGATION OF COMPOUNDS OF INTEREST

The present invention relates to a process for the preparation of a first compound of interest C1 functionalized with a sydnone compound and to the corresponding functionalized C1 compound of interest. The present invention also relates to a process for the preparation of a conjugate of two compounds of interest C1 and C2 implying a sydnone compound and to the obtained conjugate. The present invention also relates to a process for preparing a compound of interest C2 comprising a strained alkyne moiety functionalized with a sydnone and to the corresponding functionalized compound of interest C2. It also relates to novel sydnone compounds substituted in position 4, which may be used in the above processes.
