Direct geminal diallylation of lactones, lactams and acyclic amides containing a N–H bond has been achieved in the presence of allylsamarium bromide. By applying this method, quaternary carbons have been constructed, and 2,2-diallylated cyclic ethers, 2,2-diallylatednitrogenheterocycles and diallylated amides were synthesized in moderate to good yields under mild conditions.
