The rhodium (I) catalysed tandem hydrosilylation-intramolecular aldol reaction provides a simple strategy for construction of a range of usefully functionalised five-membered rings from readily prepared 6-oxo-2-hexenoates in good yield and with good to excellent stereoselectivity. A series of silanes and rhodium catalysts have been investigated. Stereoselectivity proved to be highly dependant on the
