Alkoxy derivatives of 6-chloro-2-methoxy-9-methylacridine 1 have been attached to oligonucleotides 6-10. The coupling step may be performed either with phosphoramidite-, H-phosphonate or phosphodiester reagents prepared from 2. This dye, in contrast to 9-aminoacridines, is completely stable under the conditions of oligonucleotide deprotection (NH3 or CH3NH2). The dye conjugates tightly bind to complementary strands and are useful tools in the study of nonenzymatic oligomerizations of ribonucleotides according to L. Orgel.
