We report new conditions to facilitate the addition of dianions of carboxylic acids to epoxides as an alternative method to the use of aluminum enolates. These conditions require the use of a sub-stoichiometric (10%) amount of amine for dianion generation and the previous activation of the epoxide with LiCl. Other Lewis acids have been shown to be less effective. Yields are good but only low diastereoselectivity is attained, which has not been controlled despite attempts at optimization.

A general method is proposed for the investigation of the rearrangements of unsaturated compounds with the use of stable isotopes.By means of the 13C label it was shown that the Curtius rearrangement of 1,3-diphenyl-2-propene-1-carbonyl azide takes place
