Popis: | Acid treatment of β-(3-acetoxyindol-2-yl)-α-cyanoacrylic acid derivatives (ethyl ester and nitrile) with aqueous or gaseous HCl afforded novel 3-substituted 2-oxo-2,5-dihydropyra-no[3,2-b]indoles. 2-Oxo-2,5-dihydropyrano[3,2-b]indole-3-carbonitrile was converted into ethyl 2-oxo-2,5-dihydropyrano[3,2-b]indole-3-carboximidate. |
