Synthesis of 3,4-dihydrospiro[2H-1-benzopyran-2,2'-bicyclo[2.2.1]heptane] ring system

Article abstract of DOI:10.1080/00397919208021075

Camphene oxide reacted with dilithiated o-methoxyphenylacetic acid to yield selectively the exo isomer of a spiro[γ-lactone-2,2'-bicyclo[2.2.1]heptane] which was stereoselectively converted into the exo-3,4-dihydrospiro[2H-1-benzopyran-2,2'-bicyclo[2.2.1]
