The synthesis of fused norbornene analogues containing silicon and oxygen atoms in bridgehead positions is reported. This novel type of compound can be readily obtained in stereospecific Diels-Alder [4+2] cycloaddition of siloles with oxanorbornene derivatives as appropriate dienophiles by the use of high pressure (9 kbar).
