✦ Synopsis

Abstract

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.

## Abstract ^1^H and ^13^C NMR chemical shifts of α‐ and β‐anomers of adenosine, 2′‐deoxyadenosine and their acetate derivatives were completely and definitely assigned using the concerted application of one‐ and two‐dimensional experiments (gCOSY, gNOESY, gHSQC and gHMBC). The influence of the ste
