the novel cyclopropane carboxylic acid 12. What is more significant is that although the formation of the trans-lactone on the whole is favoured in the ring opening of epoxides 4, at least in two cases, 4b and 4c, there is considerable formation of cis-lactones, a result that remains unexplained. Attemptedsynthesis of the model cis-lactone 3c always resulted in the formation of a 1:1 mixture of the
