The synthesis of iso-cytidine and 2'-deoxy-iso-guanosine phosphoramidi
tes in protected form is described. The synthesis of complementary dod
ecanucleotides containing a central iso-C-iso-G base-pair was achieved
. It is found that the iso-C-iso-G base-pair has comparable stability
to a C-G base-pair.
