Aplicaciones

2,4,6-Triisopropylbenzenesulfonyl chloride is used for the synthesis of glycerophospholipids as a condensing agent and in the analysis of phosphonolipids in egg yolk by HPLC/MS technique. It acts as a coupling reagent for the synthesis of oligonucleotides and as sulfonates of pyrimidine nucleosides. It also serves as a condensing agent in the synthesis of hydrogen-phosphonate diesters.

Notas

Incompatible with strong bases.

Hindered sulfonyl chlorides have found use as condensing agents for the formation of the phosphate link of oligonucleotides. For reviews, see: Angew. Chem. Int. Ed., 11, 451 (1972); Synthesis, 222 (1975); Chem. Rev., 77, 183 (1977). For reviews of oligonucleotide synthesis by the phosphotriester method, see: Heterocycles, 7, 1197 (1977); Tetrahedron, 34, 3143 (1978). For use as a condensing agent in the synthesis of H-phosphonate diesters, see: Nucleosides Nucleotides, 7, 23 (1988). More hindered in comparison with, e.g. Mesityl­ene-2-sulfonyl­ chloride, A11775, and so has less tendency to react with the free 5'-hydroxyl group of sugars: J. Am. Chem. Soc., 88, 829 (1966).

For examples of the utility of the triisopropylbenzenesulfonyl group in the protection of OH groups, see: J. Am. Chem. Soc., 117, 5693, 5776 (1995): (first synthesis of a digitalis saponin and asymmetric synthesis of (-) and (+)-strychnine, respectively).
