Tandem radical cyclizations of acylsilanes with alkene or alkyne functionalities attached to silicon afforded cyclic silyl ethers which were oxidatively hydrolyzed to give diols or ketone alcohols.
The study of intramolecular tandem radical cyclizations of acylsilanes with radicalphiles attached on silicon

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
The stereoselective synthesis of oxetanes; exploration of a new, Mitsunobu-style procedure for the cyclisation of 1,3-diols

A solution of 2-methyl-3-[1-(phenylsulfanyl)cyclohexyl]propane-1,3-diol 1 in toluene treated with triphenyl-phosphine, Ziram 2 and DEAD, gave 3-methyl-2-[1-(phenylsulfanyl)cyclohexyl]oxetane 3 in 85% yield. A mechanistic study has been undertaken, optimal conditions have been found and the range of substrates for which the reaction is useful has been explored. We include the results of an X-ray study which shows that compound 33 (the oxidation product of diol 1) is a sulfone rather than a sulfoxide as previously reported.
