pubmed:abstractText |
The efficiencies and problems of sulfonation of several condensing reagents for deoxyoligoribonucleotide synthesis have been studied. While 2,4,6-triisopropylbenzenesulfonyl chloride (TPSC1) gave very low yield and slow rate of coupling, the new 1:3 mixture of TPSC1 and tetrazole afforded excellent yield and extremely fast rate of reaction with the lowest rate of sulfonation. The difference and advantages of this mixture over triisopropylbenzenesulfonyl tetrazole (TPSTe) and mesitylenesulfonyl tetrazole (MSTe) are discussed. Mechanisms for the coupling reactions with these condensing reagents to account for the difference in their rates and yields of coupling are discussed.
