Abstract
An efficient, one – pot three component synthesis of novel stable phosphorus ylides has been developed from the reaction between triphenylphosphine and dialkyl acetylenedicarboxylates in the presence of 2-nitrocyclohexanone. The resulting phosphorus ylides when heated in toluene afforded dialkyl 2-(2-nitrocyclohex-1-enyl)fumarate derivatives through intramolecular Wittig reaction.
