摘　　要：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.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.
