✦ Synopsis

A polycrystalline sample of a new polymorph of the title compound, C~8~H~11~NO~2~, was produced during a variable-temperature X-ray powder diffraction study. The crystal structure was solved at 1.67 Å resolution by simulated annealing from laboratory powder data collected at 250 K. Subsequent Rietveld refinement yielded an R
~wp~ of 0.070 to 1.54 Å resolution. The structure contains two molecules in the asymmetric unit, which form a C
^2^
~2~(8) chain motif via N—H...O hydrogen bonds.

The biotransformation of (^)-bicyclo [3.3.1]nonane-2,6-dione by Aspergillus niger and Glomerella cingulata was investigated. The diketone was reduced to the ketoalcohol 2-endo-hydroxy-bicyclo[3.3.1]nonane-6-one and the diol endo,endo-bicyclo[3.3.1]nonane-2,6-diol respectively. Endo,endobicyclo[3.3.1
