A NOVEL PROTECTING STRATEGY FOR INTERNUCLEOSIDIC PHOSPHATE AND PHOSPHOROTHIOATE GROUPS
摘要:
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.
