Oligomerization aiming at phosphonate analogues of oligoadenylates.

This work deals with isopolar, phosphonate-based nucleotide analogues containing a bridging P-C bond instead of the ester P-O linkage. Specifically, starting from activated derivatives 1, 2, and 3, a simple process for preparation of mixtures of short oligomers and their analyses were elaborated.

Isosteric phosphonate pyrrolidine-based dinucleoside monophosphate analogues.

A novel alpha- and beta-configured pyrrolidine nucleoside phosphonates in adenine series were synthesized from trans-4-hydroxy-L-proline as starting material. d(ApA) analogues were also prepared and studied with respect to their hybridization properties with polyU.
