| abstract |
The invention relates to a method of simultaneously protecting two functions which are the same or different, namely hydroxyl, amine, or thiol groups, particularly in sugars, polyalcohols, nucleosides, nucleotides, peptides, and nucleic acids and to compounds protected using this method. The method of simultaneously protecting two hydroxyl, amine, or thiol functions according to the invention is carried out by reacting the two functional groups with the disilane of formula 1, thereby forming a disilane-1,2-diyl residue, where R stands for CI or Br, or I, or a substituent of formula 2, where X1, X 2, X 3, X 4 are the same or different and are N, CH or C-R1. |
