Photochemical reactions part 26 molecular and crystalline structure of a cyclo butane cyclized gibberellin derivative



Photochemical reactions part 26 molecular and crystalline structure of a cyclo butane cyclized gibberellin derivative



Tetrahedron 32(16): 2021-2026



By X-ray analysis the structure and molecular packing of the cyclobutane annelated pseudogibberellin A1 derivative, prepared by a trifluoroacetic acid catalyzed Wagner-Meerwein rearrangement was established. The 1,2-cyclobutane ring fusion as well as the configuration of the 3-hydroxy group was determined and confirmed earlier suggestions. The final discrepancy R was 0.079.
