Fully deprotected oligodeoxynucleotides containing 6-chloropurine have
been synthesized and used in solution phase reactions with amine nucl
eophiles to prepare oligonucleotides containing substituted adenine re
sidues. This strategy was used for the preparation of a double-strande
d oligonucleotide crosslinked by a 4-carbon tether between N-6 positio
ns of deoxyadenosines in the two strands. (C) 1998 Elsevier Science Lt
