A ‘click chemistry’ approach to the efficient synthesis of modified nucleosides and oligonucleotides for PET imaging
摘要:
Different thymidine derivatives bearing either an iodoaryl moiety at the 5' position or a dialkylsilyl group at the 3' position have been efficiently synthesized as precursors for carbon-11 or fluorine-18 labeling, respectively. Furthermore, iodoarylated thymidine derivatives have been incorporated into oligonucleotides giving an original way to label them with carbon-11. (C) 2009 Elsevier Ltd. All rights reserved.
