Abstract: We recently reported the asymmetric synthesis of the two title compounds without the configurational assignments of the newly formed chiral spirocarbons. We now wish to report that both compounds have a (R)-configuration at the spirocarbon based on 1D and 2D nuclear Overhauser enhancement (nOe) experiments.
Keywords: Spiroannulation; stereochemistry; nOe; NMR; absolute configuration
