Synthesis and Base Pairing Properties of Platinum(II) Nucleosides Based on Uracil

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

The synthesis and base pairing properties of platinum complexes based on uridine and deoxyuridine nucleosides are described. The synthesis was performed by C–I oxidative addition with protected and unprotected nucleosides. The metallated compounds feature an agostic interaction at H6. Uridine complexes undergo self-base pairing and also establish base pairs with adenosine. The formation of an intermolecular N-H-Pt bond is also observed
