Iodocarbocyclization of α-iodocycloalkanones bearing an allenyl side chain: synthesis of spirocyclic cycloalkanones
摘要:
AlCl3/ICl-mediated iodocarbocyclizations of alpha-iodocycloalkanones bearing an allenyl side chain are described. Treatment of iodocycloalkanones 4a-i with AlCl3/ICl gave spirocyclic cycloalkanones 5a-i and 6a-i as a mixture of products. (c) 2005 Elsevier Ltd. All rights reserved.

Samarium(II) iodide has proven to be an effective reagent for intramolecular reductive coupling reactions. Previous investigations of intramolecular ketyl−olefin coupling reactions provided carbocycles in excellent yield and good diastereoselectivity. This method has been extended to ketyl cyclizations with allenes. Substrates leading to both carbocycles and heterocycles in a selective manner are explored
