The use of hydrazinedithiocarbonate (HDTC) for the removal of chloroacetyl and bromoacetyl groups is described. The advantage of this reagent is the selective deprotection under mild conditions, which was demonstrated on carbohydrate derivatives.

A new test was elaborated to identify a new set of orthogonal protecting groups. With the developed method eight different protecting groups were tested under various deprotection conditions and the complex reaction mixtures were analysed by HPLC. The developed method allows for quick identification of orthogonality using simple model structures. (C) 2015 Elsevier Ltd. All rights reserved.
