Abstract

Radical cyclizations of acylsilanes with radicalphilic pendant introduced on silicon proceeded in a tandem fashion to give spiro products containing a cyclic silyl ether skeleton. Because the alkoxysilyl group can be replaced with a hydroxy group through oxidation, the spiro silyl ethers can be converted into diols. In the case with a radical intermediate carrying 2-oxa-3-sila-6-heptenyl skeleton, products derived from 1, 7-endo cyclization were ...
