✦ Synopsis
Considerable attention has been recently focussed on methods for specific synthesis of polyribonucleotides containing the 3'+5* interribonuclectide bonds, especially of dinuclactides and bi.ochemically important l-4 trinucleotides. Generally applicable methods havs been developed, making it possible to prsnsro all the dinurlcoside monophos:)h.ates or trinucleoside diphosphates, derived from the four principal ribonucleotiPes5.
These several-step synthetic processes require a temporary protecting of prsselzcted pooitione of the reacting nucleotide 01' di.nucleotide and

the solid compound occurred at 1686cm-1 and 1727cm-1 and before crystallisation (measured as film) at 1703 cm-1 and 1735 cm-1. Compounds IIIa-c were isolated by distillation at bath temperatures of 70-120°C and pressures of about 10-2mmHg.
The reactions of a ribonuclease model substrate, the compound uridine-3'-p-nitrophenyl phosphate, have been examined using heavy-atom isotope effects and stereochemical analysis. The cyclization of this compound is subject to catalysis by general base (by imidazole buffer), specific base (by carbona
