- TRIS(2,4,6-TRIBROMOPHENOXY)DICHLOROPHOSPHORANE: A NOVEL CONDENSING AGENT FOR RAPID INTERNUCLEOTID BOND FORMATION IN THE PHOSPHOTRIESTER APPROACH
-
A new class of condensing agent, Tris(2,4,6-tribromophenoxy)-dichlorophosphorane (BDCP), was applied to the oligodeoxyribonucleotide synthesis.This reagent enabled us to perform a rapid internucleotidic bond formation in the phosphotriester approach only
