A nucleoside with two nucleobases, a so-called double-headed nucleoside, 5'(S)-C-(thymine-1-ylmethyl)thymidine 3, is synthesised and incorporated into oligonucleotides. The additional nucleobase is hereby positioned in the minor groove of the duplexes, which are formed with complementary DNA and RNA-sequences. Slight thermal destabilisation of these duplexes as compared to unmodified duplexes is observed
