title: Dialkylformamidine protected deoxyadenosine phosphoramidites in oligonucleotide synthesis.
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 oligonucleotides, with rapid and complete deprotection at 65 degrees C in one hour. Different times and temperatures of exposure to concentrated ammonium hydroxide were examined to establish the optimum conditions for deprotection of oligonucleotides.
