A new experimental approach to the synthesis of polydeoxyribonucleotides via the phosphotriester method involves construction of oligonucleotide blocks by direct use of the easily prepared barium salts of O5',N-protected deoxyribonucleoside-3' p-chlorophenyl phosphates as the key monomers in condensation reactions. The procedure has been demonstrated by the rapid synthesis in high yield and purity of all sixteen fuly protected dinucleotides (Formula: see text) (where dN' = dT, dbzC, dbzA, or dibG; (Formula: see text) This set of molecules constitutes a "syllabary" for the preparation of defined sequence oligonucleotides.
