Yl. Chen et al., ALKOXIDE-ACCELERATED [1,3] SIGMATROPIC SHIFT OF BICYCLO[3.2.1]OCT-6-EN-2-OLS TO 8-ENDO-HYDROXYBICYCLO[3.3.0]OCT-2-EN-4-ONES, Journal of the Chinese Chemical Society (Taipei), 45(5), 1998, pp. 649-653
Bicyclo[3.2.1]oct-6-en-2-ols 6 are shown to undergo [1,3] sigmatropic
shift to afford 8-endo-hydroxybicyclo[3.3.0]oct-2-en-4-ones 8 under th
e influence of potassium hydride.
