The decarboxylative Claisen rearrangement (dCr) reaction of 1-(furan-2-yl)ethyl 2-tosylacetate afforded 2-ethylidene-3-(tosylmethyl)-2,3-dihydrofuran. Reaction of the dearomatised heterocycle with a variety of electrophiles gave addition products With excellent syn-diastereoselectivity. The furanol adducts were then utilised as functionalised scaffolds for a series of subsequent transformations. (C) 2009 Elsevier Ltd. All rights reserved.
