Novel P(III) bisamidite reagents as phosphorus protecting groups, nucleoside phosphoramidite intermediates, and synthetic processes for making the same are disclosed. Furthermore, oligomeric compounds are prepared through the protection of one or more internucleosidic phosphorus functionalities, preferably followed by oxidation and cleavage of the protecting groups to provide oligonucleotides.

The utility of 2-(N-isopropyl-N-anisoylamino)ethyl group for protection of internucleosidic phosphate linkages in oligonucleotide synthesis was studied. The group demonstrated high coupling yields, favorable deprotection kinetics and a high hydrolytic stability of phosphoramidite building blocks. The mechanism of deprotection was established using a model phosphate triester.
