The title compound, C(16)H(20)N(2)O(2), was obtained by catalytic asymmetric cyclo-addition of trans-3-propyl-acrolein with 1-benzyl-idenepyrazolid-3-one betaine. There are two symmetry-independent mol-ecules in the asymmetric unit. In both mol-ecules, the two five-membered heterocyclic rings adopt envelope conformations.
