Publikováno v: Chemistry of Heterocyclic Compounds. 24:83-86

Carbocyanine dyes with an o-hydroxyaryl substituent in the meso position of the polymethine chain were obtained from o-hydroxybenzoyl derivatives of the Fischer base and heterocyclic methylene bases (1,3,3-trimethyl-2-methyleneindoline, 1-ethyl-4-met

Autor: L. N. Kurkovskaya, L. I. Kon'kov, V. F. Mandzhikov, N. M. Przhiyalgovskaya

Publikováno v: Chemistry of Heterocyclic Compounds. 23:1078-1081

Enaminohydroxyketones, formed from 1,3,3-trimethyl-2-methyleneindoline and ortho-acetoxyaromatic acid chlorides, are converted by heating with phosphorus oxychloride in dichloroethane and subsequent treatment with alkali to 4-chlorosubstituted spirop
