title: A facile synthesis of 5'-end solid-anchored, 3'-end free oligodeoxyribonucleotides via the (5'-->3')-elongated phosphoramidite strategy.
abstract: It is demonstrated that not only N2- but also O6-protection of the guanine base is necessary for obtaining the oligodeoxyribonucleotides in high yields and at a high purity in the solid-phase synthesis via the (5'--> 3')-chain elongated phosphoramidite approach.
