Abstract

Abstract DMTrTp (SPh) 2 was proposed as a simplest “nucleotide unit” for the synthesis of olygothymidylates. One phenylthio group was removed selectively and rapidly from dithiol- esters by 1 M pyridinium hypophosphonate. Two kinds of arenedisulfonyl chlorides were newly prepared and utilized as promising condensing agents.
