A new domino autocatalytic reaction of imines with Meldrum's acid was described. In this reaction, a series of polycyclic spiro[5.5] undecane-1,5,9-trione and dispiro[4.2.5.2]pentadecane-9,13-dione derivatives, with remarkable diastereoselectivity, were successfully synthesized in acidic condition, and up to six new bonds were formed accompanied by the C=N bond cleavage of the imines and the decomposition of Meldrum's acid, with by-product of acetohydrazide as a novel autocatalyst.
