Provided herein are methods for site selective chemical modification of an oligonucleotide comprising immobilizing the oligonucleotide on an inert resin to form oligonucleotide-resin complex; and contacting the oligonucleotide-resin complex with a phosphorus (V) based phosphorus (V) reagent in an organic solvent to produce a modified oligonucleotide. Further provide herein are methods of targeting delivery of an oligonucleotide therapeutic to a specific location in the patient body, and/or improving stability and half life of an oligonucleotide therapeutic by using modified oligonucleotides.
A compound of formula (I) is described
and use thereof as fragrance, especially as lily-of-the-valley fragrance and/or as an agent for increasing the substantivity and/or the retention of a fragrance preparation and/or as a fixative.

The first practical, fully stereoselective P(V)-radical hydrophosphorylation is presented herein by using simple, limonene-derived reagent systems. A set of reagents have been developed that upon radical initiation react smoothly with olefins and other radical acceptors to generate P-chiral products, which can be further diversified (with conventional 2e– chemistry) to a range of underexplored bioisosteric
