Development of a Flexible and Robust Synthesis of Tetrahydrofuro[3,4- b]furan Nucleoside Analogues

In the context of a PRMT5 inhibitor program, we describe our efforts to develop a flexible and robust strategy to access tetrahydrofuro[3,4-b]furan nucleoside analogues. Ultimately, it was found that a Wolfe type carboetherification from an alkenol derive

Synthesis of the 3′-C-hydroxymethyl-branched locked nucleic acid thymidine monomer

A 3′-C-hydroxymethyl-branched Locked Nucleic Acid (LNA) monomer 3 was synthesized from diacetone-α-D-glucose taking advantage of a stereoselective Grignard reaction for the introduction of a vinyl group, an aldol/Cannizzarro sequence for introducing the 4

New ruthenium-based protocol for cleavage of terminal olefins to primary alcohols: Improved synthesis of a bicyclic nucleoside

A new protocol for the oxidative cleavage of terminal alkenes to give exclusively primary alcohols in high yields is introduced. The protocol is based on RuO4-mediated dihydroxylation, NaIO4-mediated diol cleavage, and NaBH4-mediated reduction, but the introduction of a reducing step before the diol cleavage removes the formation of byproducts and improves the yield significantly. The new protocol has been developed and used for the improved preparation of a [3.2.0]bicycloarabinonucleoside with important potential in antisense and antigene technology.
