The synthesis of 1-substituted 5-hydroxy-2-phenylindole derivatives from quinones
Abstract
Ethyl β-benzylaminocinnamate and ethyl β-n-butylaminocinnamate have been prepared and condensed with benzoquinone, toluquinone, and 1,4-naphthoquinone to give 1-substituted 5-hydroxy-2-phenylindole derivatives. 1-Benzyl-5-hydroxy-2-phenylindole and 1-n-butyl-5-hydroxy-2-phenylindole have been synthesised.
