allylic silanes bearing additional functionality in the form of either a bromide or a phenylsulphonyl group were synthesised and condensed with a variety of electrophilic partners. Subsequent cyclisation of some of the products was then possible by utilising the acid-promoted reactions of the allylsilane grouping, to give one spiropentannulated product (8) and two medium ring ether sulphones (12) and
