Oligonucleotide synthesis

Oligonucleotide synthesis

In the early 1950s, Alexander Todd's group pioneered Hphosphonate and phosphate triester methods of oligonucleotide synthesis. The reaction of compounds 1 and 2 to form Hphosphonate diester 3 is an Hphosphonate coupling in solution while that of compounds 4 and 5 to give 6 is a phosphotriester coupling (see phosphotriester synthesis below).
