✦ Synopsis

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 insertion and cyclopentyl spiroannulation.
