Abstract
4-Phenyl-3,4-dihydro-1,5-benzodioxepin-2-one, on treatment with lithiu m diisopropylamide (LDA), undergoes fission of the heterocyclic ring t o afford catechol monocinnamate. Similar reaction in the presence of c ertain aldehydes, however, results in double fission of the heterocycl ic ring, yielding cinnamate esters.
