摘要

The acid-catalyzed rearrangement of [5.3.2]- and [5.4.2]propella-e-lactones 9 and 10 in boiling acetic acid takes place readily to afford the 1,2-disubstituted cyclopentene 21 and cyclohexene 26 as the major products, respectively, while such lactone ring cleavage of the [4.3.2]- and [4.4.2]propella-δ-lactones 1 and 2 does not occur at all under similar conditions. The remarkable distinction in reactivity in the acid-catalyzed rearrangement between the e-lactones and the δ-lactones is attributed to the effect of lactone ring size.
