Highly Functionalized Cyclopentanes by Radical Cyclization of Unsaturated Bromolactones. Part 3. Preparation of Carbaaldohexofuranoses. Determination of the Relative Configuration at C-4/C-5 or 2,3-Unsaturated Heptono-1,4-lactones by Means of 1 H NMR Spectroscopy.
-Key step in the synthesis of carbasugars [cf. (V)] is a highly stereoselective intramolecular 5-exo-trig radical cyclization of the unsaturated bromo-1,4-lactone (II). -(HORNEMAN,
