Abstract
A process for the preparation of biologically active silicon compounds by hydrolysis of a precursor which produces a compound which prevents the formation of polymers from the silicon hydrolyzed bonds.
Claims21
A process for the preparation of a silyl biologically active compound, comprising hydrolyzing a precursor having the formula:
- in which A, B, C, D and X indicate radicals different from OH, and the linkages of A, B, C, D with the Si atom are covalent bonds and 2 or 3 of these bonds are hydrolysable,
- wherein the hydrolysis is carried out in an aqueous solvent and at least one compound obtained is a stabilizing compound which prevents the formation of polymers from the silicon hydrolyzed bonds.
