X-ray structural investigation of a derivative of the alkaloid kesselringine

The molecular and crystal structures of 2,6-dimethyl-12-demethylkesselringine methosulfate have been determined by x-ray structural analysis. The relative configurations of the chiral centers in the R, S nomenclature have been established.Institute of Bioorganic Chemistry, Academy of Sciences of the Uzbek SSR, Tashkent; V. I.
