Abstract

equation presented A 1% cross-linked divinylbenzene-polystyrene copolymer, containing cyanoethoxy N,N-diisopropylamine phosphine was prepared as a phosphitylating agent. The polymer-bound phosphitylated precursor was subjected to reaction with alcohols in the presence of 1H-tetrazole to produce the corresponding polymer-bound phosphite triesters. These were then oxidized with tert-butyl hydroperoxide to give the polymer-bound monophosphate triesters. Removal of cyanoethoxy on the resin with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) followed by basic cleavage of the p-hydroxybenzyl linker products yielded monophosphate derivatives.
