Abstract

The title compounds, C 28 H 30 O 10 and C 14 H 10 O, have been synthesized during the course of a program designed to prepare molecules with DNA-cleaving properties. The geometry of the strained benzodiyne system has been determined, the S configuration at the propargylic center established and the orientation of the sugar unit in relation to the aglycon defined. The results are compared with those for other derivatives. The molecular packing is governed by normal van der Waals interactions
