The Synthesis of Carbocyclic 5′-Nor Thymidine and an Isomer as Oligonucleotide Monomers
摘要:
The chiral synthesis of (1S,3S,4S)-1-(3,4-dihydroxycyclopent-1-yl)-1H-thymine (carbocyclic 5'-nor thymidine, 4) has been achieved in 5 steps from (+)-(1R,4S)-4-hydroxy-2-cyclopenten-1-yl acetate (5) and N-3-benzoylthymine. Compound 4 is viewed as a monomeric building block for poly-T-like oligomers.
