An efficient and practiced procedure for the preparation of gamma-oxo esters from the beta-azidocyclopropane esters has been developed. Ph3P was proven to be a good promoter in THF/H2O, and 11 gamma-oxo esters were prepared in 73-99% yields under mild and neutral conditions. (C) 2013 Elsevier Ltd. All rights reserved.
