ChemInform Abstract: Diels-Alder Reactions of 1-Phenylpyrano(3,4-b)indol-3-ones with Alkynes: New Functionalized Carbazoles.

1990

3-Indolylalkanoic acids 2 react with benzoic acid anhydride under catalysis of Et2O - ZnCl2 and mild conditions to furnish the 1-phenyl-substituted pyrano[3,4-b]indol-3-ones 1c, 1d, and 3a, 3b. Products 1c, 1d, and 3b may be converted into the novel functionalized carbazoles 4 and 5 by reaction with acceptor-substituted alkynes.

First synthesis of chiral 3-vinylindoles as 4π-components for diels-alder reactions

1995

The first syntheses of chiral 3- and 2-vinylindoles bearing sulfoxide or (-)-menthyloxy functional groups at the β-vinyl positions by way of procedures based on the Horner-Wadsworth-Emmons and Wittig reactions, respectively, are described. Some Diels-Alder reactions demonstrating the 4π-reactivity of these compounds are reported.
