Abstract

In the recent years, protection of NДH bonds in nitrogen-containing heterocycles by introduction of a triphenylmethyl (trityl) group has received increasing application. For this purpose, chlorotriphenylmethane or its functional derivatives are generally used, and the reaction is carried out in anhydrous solvents and in an inert atmosphere or, as recently proposed [1], under conditions of phase-transfer catalysis.
