A highly stereoselective method for the synthesis of functionalized 3‐oxabicyclo[3.3.1]nonan‐2‐one derivatives with four contiguous stereogenic centers, including one tetrasubstituted stereogenic center, was realized through an organocatalytic domino Michael‐hemiacetalization‐Michael reaction of (E)‐3‐aryl‐2‐nitroprop‐2‐enols and (E)‐7‐aryl‐7‐oxohept‐5‐enals followed by a PCC oxidation. Using the...
