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

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.
