Abstract
Abstract The spiro[3,4-dihydro-2H-1-benzopyran-2,2′-bicyclo[3.1.1]heptane] framework of natural products Robustadials was constructed in a homochiral form. The synthesis started from 1 S -(−)-β-pinene, which was coupled to a substituted benzaldehyde using a Prins reaction, and incorporated a diastereoselective, Michael-type, intramolecular addition.
