S. Wendeborn et al., REPLACEMENT OF THE PHOSPHODIESTER LINKAGE IN OLIGONUCLEOTIDES BY A C=C DOUBLE-BOND - COMPARISON OF THE CIS AND TRANS ISOMERS, Tetrahedron letters, 36(38), 1995, pp. 6879-6882
The two olefinic backbone replacements III and IV were synthesized and
incorporated into oligonucleotides. The hybridization properties of t
he modified oligonucleotides to DNA and RNA complements and conformati
onal analyses of III and TV are compared to the corresponding amide mo
difications I and II.
