Zinc mediated Barbier type allylation of cyclic imides and subsequent coupling reactions with carbon nucleophiles

reactions with various carbon nucleo-philes to afford in highly fnctionalized 5,5-disubstitutedisoindolones, spirocyclization compound. We also foundthat β-diketone as carbon nucleophile can be used asprecursors for a π-nucleophilic attack onto allylated hydroxylactams, giving 1,2-addition products. So, allylated hydroxylactams have proven a useful
