Stereoselective cyclopropanation in the synthesis of 3'-deoxy-3'-C-hydroxymethyl-2',3'-methylene-uridine. 2014
The synthesis of the novel 2',3'-cyclopropane nucleoside 3'-deoxy-3'-C-hydroxymethyl-2',3'-methylene-uridine is described. Stereoselective construction of the cyclopropane ring was achieved via Simmons-Smith cyclopropanation of a benzyl protected silyl enol ether, which was itself derived from 1,2-O-isopropylidene-α-D-xylofuranose.
