The diastereomeric carbenoids 4 have been generated by diastereoselective (84:16) exchange of the diastereotopic bromine atoms in the dibromo compound 3 for lithium at -120 deg C.The implication of the observed diastereoselectivity for the Nozaki ring-expansion method is discussedKey words: Carbenoids / Halogen-metal exchange / Diastereotopic groups
