The title compound has been synthesized stereoselectively based on a new methodology for the construction of erythro-1,3-diols. Endo-1,3-dimethyl-2,9-dioxabicyclo[3.3.1]nonane (11, first isolated by Heemann and Francke in 1976 from Norway spruce attacked by the ambrosia beetle (Tgypodendron Lineatum
## Eingegangen am 6. Februar 1984 Von substituierten 3-0xa-7-azabicyclo[3.3.l]nonan-9-onen abgeleitete tertiare Alkohole werden durch Grignard-Reaktion der Ketone mit Propargylmagnesiumbromid erhalten. Die Stereoselektivitat dieser Reaktioncn ist sehr hoch. 'H-NMRund IR-Spektren werden diskutiert.
The solvolysis rates of a series of tertiary&-aryl-substituted cycloalkyl chlorides were recently determined (1). This series did not include 9-substituted-bicyclo(3.3.1)nonanes, the only available data being on the acetolysis of secondary tosylates, from which many rearranged products are obtained
