Nucleoside-metallacarborane conjugates - synthesis of a uridine - bearing 3,3,3-(CO)3-closo-3,1,2-ReC2B9H10 complex

Abstract

A new type of nucleoside-metallacarborane conjugate is presented. 3,3,3-Tricarbonyl-closo-3,1,2-ReC 2 B 9 H 10 is used as a modifying unit. The method is based on the de novo formation of a metallacarborane complex via the reaction of [NEt 4 ] 2 [ReBr 3 (CO) 3 ] with the uridine-bearing carborane as a boron cluster ligand. The uridine-tricarbonyl rhenacarborane represents an example of a novel type of nucleoside-metallacarborane conjugate bearing a therapeutically important rhenium component.
