A New Method for the Synthesis of Oligodeoxyribonucleotides Containing 4-<i>N</i>-Alkoxycarbonyldeoxycytidine Derivatives and Their Hybridization Properties
experiments apparently showed that incorporation of 4-N-alkoxycarbonyldeoxycytidines into DNA strands resulted in higher hybridization affinity with the complementary DNA strands than that of 4-N-acyldeoxycytidines. In addition, comparable T(m) studies using oligodeoxyribonucleotides incorporating acyl (RC(O)-) groups and alkoxyacyl (RO(CH(2))(n)C(O)-) groups having the same chain length show that the
