摘要
Treatment of 3,4-epoxy-6-substitutedhex-5-yn-1-ols with BF3.OEt(2) gave-the endo-mod cyclization products with inversion of stereochemistry, whereas conversion of the epoxides to the corresponding hexacarbonyldicobalt complexes, followed by Lewis-acid treatment provided the endo-mode products with retention of configuration at the newly formed stereogenic centre.
