The 1 H and 13 C NMR chemical shift assignments of hydroxycyclopentylpropenone derivatives, prepared by a highly selective reaction between samarium(II) iodide and unsaturated ketones, are described. Two‐dimensional shift‐correlated experiments (COSY, HMBC, HMQC, NOESY) were used to assign the chemical shifts completely and unambiguously. Copyright © 2001 John Wiley & Sons, Ltd.
