The chromium Fischer carbene complexes of benzofuran and benzothiophene have been prepared and can be used in D?tz benzannulations with alkynes for the regioselective and converg ent synthesis of dibenzofuran-1,4-dione heterocycles. The use of alkynylboronates led to model systems of the tricyclic ring system of popolohuanone E after oxidation. It would appear that the combination of alkynyl boronates with furan type Fischer carbene complexes leads to substantial amounts (～50%) of protodeboronated products.

The oviposition stimulant for the lesser mulberry pyralid, Glyphodes pyloalis WALKER, was isolated from an acetone extract of mulberry (Morus alba L.) leaves, and its structure was identified as 2-(3',5'-dihydroxy-4'-prenylphenyl)-6-hydroxybenzofuran, viz
