Pentopyranosyl Oligonucleotide Systems: 9th Communication. The β-D-Ribopyranosyl-(4′→2′)-oligonucleotide System ('Pyranosyl-RNA'): Synthesis and Resume of Base-Pairing Properties

Pyranosyl-RNA ('p-RNA') is an oligonucleotide system isomeric to natural RNA and composed of the very same building blocks as RNA. Its generational, chemical, and informational properties are deemed to be those of an alternative nucleic acid system that c

A Convenient Method for the Synthesis of Macrocyclic Tetra-amides by Double Condensation Reaction

A facile condensation reaction between bifunctional amines and carboxylic acid derivatives has been found to be very efficient for the formation of macrocyclic tetra-amide ring, and tetralactams with 33- to 37-membered rings were readily synthesized in good yield (60-90percent).
