摘要

A very simple and efficient method is described for protection of alcohols and nucleosides withtrityl(triphenylmethyl), mono and dimethoxytrityl chlorides in the presence of triethylamine under microwaveirradiation. High selectivity was observed for tritylation of 5'-OH function of nucleosides.
