Abstract:

JandaJel resin-supported triphenylphosphine(JJ-TPP), was used as an effective organocatalyst for the [3+2] annulation reaction of alkyl 2-butynoates with electron-deficient alkenes to afford the corresponding cyclopentenes in 40%―68% isolated yields. JJ-TPP was reused after simple filtration and vacuum drying.

Key words: Organocatalysis, Polymer-supported tertiaryphosphine, [3+2] Annulation reaction
