3,4-DIDEHYDROPYRIDINE PLUS CYCLOPENTADIENE: OR -CYCLOADDITION ?

Reinecke, Manfred G.,Brown, E. Sherwood,Capehart, Bruce P.

, p. 5675 - 5680 (1988)

3,4-Didehydropyridine (2) generated from two precursors (6 and 7) of diazonium carboxylate 5 reacts with cyclopentadiene to give the -cyclo-addition product 3 rather than the -adduct 4 proposed in the literature.The structure of 3 was supported by complete proton and carbon NMR assignments made with the aid of decouling and 2D experiments
