Abstract
The sesquiterpene lactone enhydrin 1 and its derivatives 2 show extrao rdinary stability of its nuclear epoxide, which is stable under hydrol ytic oxidative and reductive conditions. The unusual stability is attr ibutable to the steric effect in 1 and the transannular hydrogen bondi ng in 2. Cleavage of this epoxide in the diol 2 and its derivatives ha ve been investigated and evidences to explain its unusual stability ha ve been reported.
