Abstract Reaction of the title nitrone I with indole derivatives IIa, b gives the 1, 3-addition product IIIa, b, its hydrogenated derivative IVa, b and dehydrogenation products VIa, b and VIIa, b from transient product of 1, 3-dipolar cycloaddition (V). Indole itself only gives cycloaddition products VIc and VIIc. Carbazole derivative VIII does not react due to sterical reasons. The reaction course is discussed on the basis of PMO theory.
