Polyacetylenverbindungen, 267. Biogenetisch interessante Acetylenverbindungen aus Cineraria saxifraga DC
Polyacetylenic Compounds, 267. – Biogenetically Interesting Acetylenic Compounds from Cineraria saxifraga DC 
 
 
 
While Cineraria aspera afforded only the typical known constitutents of this genus, C. saxifraga contains in addition to dihydrocinalyratyl acetate and isoelimicin the three C13-acetylenic compounds 3, 6, and 7 which are important intermediates in the biogenesis of polyacetylenes. The structures were elucidated by spectroscopic methods.
