Nucleoside 3'-phosphotriesters as key intermediates for the oligoribonucleotide synthesis. IV. New method for removal of 2,2,2-trichloroethyl group and 31P NMR as a new tool for analysis of deblocking of internucleotide phosphate protecting groups.
Zinc/acetylacetone/pyridine treatment has been designed as a very efficient method for removal of 2,2,2,-trichloroethyl group from phosphoesters. Internucleotide and terminal 2,2,2-trichloroethylphosphotriesters were transformed to corresponding diesters quantitatively. Much less reactive 2,2,2-tric...
