Abstract
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 dearomatized heterocycle with a variety of electrophiles gave addn. products with excellent syn-diastereoselectivity. The furanol adducts were then utilized as functionalized scaffolds for a series of subsequent transformations. [on SciFinder(R)]
