Abstract

Abstract: A one-step spiroannelation method applicable to the synthesis of the commonly encountered spirocyclic systems is described. The method involves the reaction of 3- halocycloalk-2-enones with a new type of cuprate reagent prepared from organodilithium reagents and copper thiophenoxide and is shown to provide efficient am to spiro [4.4] nonanes, spiro [4S] dmnes, and spiro [5S] undecanes. The effects of temperature, ...
