                                    Rasta resin-TBD (RR-TBD) was found to be an efficient organocatalyst for -selective Morita-Baylis-Hillman reactions between ,-disubstituted allenones and aryl aldehydes. In these reactions the heterogeneous nature of RR-TBD greatly facilitated product isolation since the catalyst could be separated simply by filtration.
