Procedures were developed for the heterocyclization of 2 benzoylethynyl 1 hydroxy and 1 hydroxy 2 (1 oxo 3 phenylpropynyl)anthraquinone. The regioselective preparation of 2 substituted anthra[1,2 b]pyran 4,7,12 triones was demonstrated to be possible under mild conditions.
Untersucht wird die Substitution der Halogenatome in den Halogenanthrachinonen (I) bzw. (III) durch die Phenylethinylgruppe in Abhängigkeit von der Natur des Halogenatoms, vom Einfluß der Substituenten im gleichen Kern, in dem sich das Halogenatom befindet, sowie von den Bedingungen der Phenylethinylierungsreaktion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
