Abstract
A simple one-pot procedure is described for the preparation of spiro[4.4]no nane-2,7-dione derivatives from open chain bis(alpha-diazoketones) by two c onsecutive intramolecular Rh(II)-catalyzed carbenoid insertion reactions. W ith 1-diazo-4-(3-oxocycloalkyl)butan-2-ones as substrates, the methodology provides 2,7-dioxospiranes with a cyclopentane ring spiroannulated onto a f ive-, six- or seven-membered cycloalkane.
