γ-Lactames having a hexatriene moiety undergo 6π-electrocyclization followed by oxidation to give 3-phosphorus ylide oxindoles, which are further oxidized to yield isoxazolidinones (III) and isatins (V).

Organophosphanes promote the [3+2] cycloaddition reactions of dialkyl (E)-hex-2-en-4-ynedioates and [60]fullerene, giving a series of cyclopenteno-fullerenes 3a–k bearing phosphorus ylides. This cycloaddition reaction is initiated by the attack of

Multicomponent reactions of phosphines, diynedioates, and aryl aldehydes have been demonstrated, providing trisubstituted furans appending reactive phosphorus ylides, through cumulated trienoates as key intermediates. The proposed trienoate intermedi
