A brief literature survey reveals that metal-free ligation such as the maleimide-based cycloaddition with electron-rich (hetero)dienes is a widespread tool for the assembly of (bio)molecular systems with applications in biotechnology, materials science, polymers and bio-organic chemistry. Despite their everyday use, only scattered data about their kinetics as well as the stabilities of corresponding products under physiological conditions, are accessible. These key parameters are yet, of paramount importance to ensure the rapid and effective preparation of stable compounds. Herein is reported a systematic study regarding the different classes of dienes used in chemoselective ligation, including their accessibility and stability, as well as comparative kinetic experiments and products stability assays. We took advantage of these data to develop a double labeling strategy from the combined use of cyclopentadiene and oxazole dienes.

The importance of chemically modified and surface immobilized nucleic acids has inspired the development of a wide variety of complementary techniques for covalent oligonucleotide preparation and immobilization. We are developing technology based on the use of a Diels-Alder reaction for accomplishing the covalent modification of oligonucleotides. Reported herein is preliminary progress toward the establishment of robust reagents for introducing the reactive functionality, as well as studies employing the BIACORE system to demonstrate surface immobilization by the method.
