  A stereoselective cyclisation cascade mediated by SmI2–H2O: synthetic studies towards stolonidiol

  摘要：

  A cascade reaction involving sequential conjugate reduction, stereoselective aldol cyclisation and chemo-selective lactone reduction mediated by SmI2-H2O provides access to a cyclopentanol bearing two vicinal quaternary stereocentres with good stereocontrol. The functionalised cyclopentanol product has been converted to a key intermediate in ongoing asymmetric studies towards stolonidiol. (C) 2010 Elsevier Ltd. All rights reserved.
