A multi-nucleating azacrown conjugate (5a) consisting of two 3,5-bis(1,5,9-triazacyclododecan-3-yloxymethyl)benzyl groups attached to 1 and 7 sites of cyclen was prepared and tested as an artificial ribonuclease. The conjugate in the presence of five equivalents of zinc nitrate expectedly showed uridine selectivity comparable to that 1,3,5-tris(1,5,9-triazacyclododecan-3-yl)benzene (2), a compound known to bind to two adjacent uridine residues and cleave the intervening phosphodiester bond. 5a was, however, unable to discriminate between two and three adjacent uridine residues, but cleaved oligonucleotides containing a UpU and UpUpU site at a comparable rate, even when present at sub-saturating concentrations.
Fully automated continuous meso-flow synthesis of 5′-nucleotides and deoxynucleotides

The first continuous meso-flow synthesis of natural and non-natural 5′-nucleotides and deoxynucleotides is described, representing a significant advance over the corresponding in-flask method. By means of this meso-flow technique, a synthesis with time consumption and high-energy consumption becomes facile to generate products with great efficiency. An abbreviated duration, satisfactory output, and mild reaction conditions are expected to be realized under the present procedure.
An RNA modification with remarkable resistance to RNase A

A 3′-deoxy-3′-C-methylenephosphonate modified diribonucleotide is highly resistant to degradation by spleen phosphodiesterase and not cleaved at all by snake venom phosphodiesterase. The most remarkable finding is that, despite the fact that both the vicinal 2-hydroxy nucleophile and the 5′-oxyanion leaving group are intact, the 3′-methylenephosponate RNA modification is also highly resistant towards the action of RNase A.
