2'-O-Tetrahydrofuranyl-5'-O-dimethoxytrityl-N-protected nucleosides were phosphorylated to give the 3'-(o-chlorophenyl) phosphates which were then condensed with 3',5'-unprotected nucleosides to elongate the chain in the 3'-direction. The 5'-dimethoxytrityl group of these oligonucleotides was selectively deblocked by treatment with zinc bromide. The rate of removal of the dimethoxytrityl group differed in each nucleotide. A dodecamer containing a termination codon UAG, U(AGU)3AG, was synthesized by elongating the chain in the 5'-direction using the selective dedimethoxytritylation followed by condensation of protected oligonucleotide blocks.
