phosphite-triester synthesis of oligonucleotides. Use of this group enables one to simplify procedures for preparing active nucleoside phosphorochloridite reagents, to remove oligonucleotide phosphotriesterintermediates intact from a solid support, and to conduct block syntheses in solution or on a silica support viaphosphite chemistry. Deprotection can be achieved by warming the trihaloethyl phosphotriesters with
