## Abstract The gasβphase thermal decomposition of 7,7βdimethylbicyclo[3.2.0]heptβ2βenβ6βone (DBH) to yield cyclopentadiene and 1,1βdimethylketene as primary products was studied in the temperature range of 470β550 Β°K using a static reaction system. Firstβorder rate constants for the depletion of D

Single crystal X-ray diffraction analysis of compounds A, B and, C helped us to assign the absolute configurations of the enantiomers of the bicyclo[3.2.0]hept-3-en-6-endo-ols 4-6. These bicyclic alcohols were easily obtained by: (i) stereoselective reductions of the bicyclo[3.2.0]hept-3-en-6-ones 1
The enzymes are stirred together with Eupergit-C (Dumas Chemicals) in 1M phosphate buffer (pH 7.5) over 96 h at 4OC. 10. 7endo-Chloro-7exo-methylbicyclo[3.2.0]hept-2~en-6-one was reduced by HSDH to give optically pure-&do-alcohol.
