| Outline of Final Research Achievements |
In this research, practical methods for molecular conjugation applicable in broad disciplines, including life science research, were developed particularly by controlling the reactivities of doubly sterically hindered aromatic azides and cyclic alkynes. We have developed a facile method to assemble three types of functional modules by three consecutive azido-type-selective triazole formations using a triazido platform molecule. We also found that thiophene S,S-dioxides serve as useful linkers, which can be used orthogonally with azides. Furthermore, we have achieved the direct thioamination of aryne intermediates, which is useful for constructing a chemical library that contains a diverse range of aromatic compounds.
