4,6-Dinitro-1-(mesitylene-2-sulphonyloxy)-benzotriazole , 1-(mesitylene-2-sulphonyloxy)-4-nitro-6-trifluoromethylbenzotriazole (6a) and 1-(mesitylene-2-sulphonyl)-4-nitro-1,2,3-triazole are more reactive condensing agents in the phosphotriester approach to oligonucleotide synthesis than 1-(mesitylene-2-sulphonyl)-3-nitro-1,2,4-triazole by factors of at least 10, ca. 4 and ca. 1.3, respectively.
Sulfonic acid esters
-
, (2008/06/13)
A novel process for the amidation or esterification which comprises reacting a compound having a carboxy group with a compound having an amino or imino group which can be acylated or with a compound having a hydroxy group in the presence of a sulfonic acid ester of the formula: wherein R1 is an organic group and R2 O-- is a residue of a strongly acidic N-hydroxy compound as a condensation agent, and a novel sulfonic acid ester useful as such a condensation agent and a process for the preparation thereof.
