Early transition metal induced intramolecular cocyclisation / elaboration reactions using a cleavable silicon linker

Article abstract of DOI:10.1055/s-1997-1059

1,6- and 1,7-dienes and -enynes incorporating a silicon-oxygen or silicon-nitrogen link are co-cyclised with zirconocene(1-butene) or diisopropoxytitanium(propene) to give metallabicycles. Further elaboration followed by cleavage of the silicon-carbon bond using Tamao oxidation affords a wide variety of organic products.
