A reaction of gamma-silyl allylic alcohol and its ether with ozone provides synthetically versatile alpha-formyl silyl peroxide in good yield without normal fission of carbon-carbon double bond. Thus, the provided silyl peroxide serves as a good precursor for the stereochemically defined triol derivative via alkylation and reduction of peroxide moiety.
The reaction of alkenylsilanes with ozone provides synthetically versatile β-hydroxy or α-formyl silyl peroxides in good yield without normal fission of the C=C bond. The obtained α-formyl silyl peroxides serve as good precursors for the stereochemically defined diol or triol derivatives via nucleophilic addition to the formyl group and reduction of the peroxide moiety.
