9-(4-Methoxyphenyl)xanthen-9-thiol: A useful reagent for the preparation of thiols
摘要:
Treatment of 5' -chloro-5' -deoxynucleosides (5) with the conjugate base of 9-(4-methoxyphenyl)xanthen-9-thiol (3b), followed by acid-promoted removal of the 5'-s-[9-(4-methoxyphenyl)xanthen-9-yl] group in the presence of pyrrole gives the corresponding 5'-deoxy-5'-mercaptonucleosides (7) in good yields.
