| Abstract: | Abstract A series of dialkylformamidine protected deoxyadenosine phosphoramidites were prepared for automated, solid-support DNA synthesis. The set of Abz, Gdmf, Cbz, T phosphoramidites gave high purity and high yield oligodeoxynucleotides, with complete deprotection at 65 °C in one hour. Different times and temperatures of exposure to concentrated ammonium hydroxide were examined to establish the optimum conditions for deprotection of oligodeoxynucleotides. |
