 Title    Zur Struktur von verbrückten Photoisomeren der Cyclodieninsektizide Structure of Bridged Photoisomers of Cyclodiene Insecticides  
 Abstract    Asymmetrically substituted chlorinated tetrahydro-4,7-methano-lH-indanes can be bridged photochemically into two types of isomerization products. These photoisomers can be distinguished on the basis of different geminal coupling constants in their X H NMR spectra. The structural assignment is not always certain, given only one photoisomer; it is unambiguous when both isomers are available.

 Title    New Triterpenoid from Primula denticulata  
 Abstract    From the alcoholic extract of the plant Primula denticulata four main compounds could be isolated by column chromatography: Pri-dentigenin A, B, C and D. Several spectroscopic methods and the synthesis of several derivatives allow to determine the structure of Pridenti-genin B.
