1-Acetyl-3-oxo-2,3-dihydroindoles were reacted with substituted benzaldehydes affording 1-acetyl-2-arylmethylene-3-oxo-2,3-dihydroindoles which were selectively reduced by hydrogen; then a Horner-Emmons reaction gave the precursors of 2-substituted tryptamines. Nitromethane was added to 1-acetyl-2-arylmethylene-3-oxo-2,3-dihydroindoles giving Michael addition products.
Oxidation of the E or Z isomers of the 1-acetyl-2-arylidene-1H-indol-3(2H)-ones 1 by dimethyldioxirane in acetone at ambient temperature led to the spiroepoxides 2 in good yield (70-90%) with complete diastereoselectivity.
