Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...

Photolysis of Heptanal

The Journal of Organic Chemistry, 2006
Photolysis of heptanal is investigated from an experimental and theoretical point of view. Photoexcited heptanal is believed to undergo rapid intersystem crossing to the triplet manifold and from there undergoes internal H-abstraction to form biradical intermediates.
