- 中文摘要: Substituted alkyl 2H-pyran-5-carboxylates condensed with alkyl 3-oxo-4-(triphenylphosphoranylidene)butanoate and alkyl 4-(triphenylphosphoranylidene)-2-butenoate to form substituted 2-vinyl-6-oxo-4-cyclohexene-1,3-dicarboxylates, some of which showed ecto-parasiticidal activity in pets and cattle, and substituted 2-vinyl-3,5-cyclohexadiene-1,3-dicarboxylates, respectively. The last mentioned product is in marked contrast to the product obtained using the corresponding arsonium analogue.
