Crimmins, Michael T. published the artcileIntramolecular photocycloaddition-cyclobutane fragmentation: total synthesis of (±)-laurenene, Formula: C7H13BrSi, the publication is Journal of the American Chemical Society (1987), 109(20), 6199-200, database is CAplus.
Nature’s only known existing fenestrane, laurenene (I) was prepared via an elevated temperature intramol. [2+2] photochem. cycloaddition of diene II. This established the highly sterically congested center of the laurenene skeleton which contains 3 contiguous quaternary C. Reductive cleavage of the cyclobutane produced during the photocycloaddition provides an intermediate which was used to form the remaining 7 membered ring via an intramol. aldol-dehydration reaction. The [5.5.5.7] fenestrane III which was prepared in 12.7% yield was transformed to I in 5 steps.
