The rhodium catalysed C-H insertion reactions of o~-(triethylsilyl)diazoacetates have been studied, facilitating the stereoselective synthesis of t~-(triethylsilyl)-y-lactones. An intriguing 'and unprecedented inversion of stereoselectivity is observed upon changing from rhodium (It) carboxylates to

A simple one-pot procedure is described for the preparation of spiro [4,4]nonane-2,7-dione derivatives from open chain bis(oc-diazoketones). The reactions proceed by an intramolecular Rh(II)carbenoid insertion into a methylene C-H bond yielding a cyclopentane which subsequently undergoes C-H methine
