Photocycloaddition-cyclobutane rearrangement to spiro cyclopentanones: application in a formal synthesis of (+/-)-α-cedrene
A novel four-step sequence has been developed for construction of cyclopentanone at the carbonyl carbon of cyclic ketones 5 leading to the synthesis of functionalised spiro systems 9.The key steps involve a pinacol-type rearrangement of ethoxycyclobu

A Novel Route to Usefully Functionalised Spiro Systems; Application to a Formal Synthesis of (+/-)-α-Cedrene
A facile route for the construction of functionalised spiro systems through pinacol type rearrangement of appropriately designed cyclobutane derivatives with an application to a synthesis of (+/-)-α-cedrene is described.
