The reaction of nitrones with various indole derivatives has been studied. When the reaction was promoted by ClSiMe 3 , the isolated products were 3,3 H -diindolylalkanes. With HCl as the activating reagent, 3-indolylhydroxylamines were isolated. The diastereoselectivity of this condensation with a
N-(Benzylidene)-and N-(2-phenylamino-2-oxoethylidene)aniline N-oxides add stereospecifically to the double bond in 4-methylene-and 4-acryloylamino-4-methyltetrahydropyrans to give substituted isoxazolidines. The use of 4-methyl-5-arylamino-and 4-arylaminomethyl-5,6-dihydro-2H-pyrans for the synthesi
