摘要：
An enolate mediated aldehyde-azomethine imine [3+2] cycloaddition of various aldehydes with N,N-cyclic azomethine imines is reported under DBU or tBuOK-catalysis. High reaction rate, ease of operation, simple catalyst, easily accessible starting materials and a wide substrate scope with numerous applications make this reaction an ideal addition to the click chemistry.
