Abstract
General methods for the synthesis of nucleosides modified with borane clusters and metallacarborane complexes are presented. These include: (1) the click chemistry approach based on Huisgen 1,3?dipolar cycloaddition and (2) tethering of the metallacarborane group to the aglycone of a nucleoside via a dioxane ring opening in oxonium metallacarborane derivatives. The proposed methodologies broaden the availability of nucleoside?borane cluster conjugates and open up new areas for their applications. Curr. Protoc.
