In the structure of the title compound, C 12 H 11 NO 4 , the two furan rings, one to a greater degree than the other, adopt envelope conformations and are twisted slightly relative to the benzene ring. The olefinic bond displays a trans configuration.
## Abstract This paper describes the synthesis of some 5‐amino‐1,2,3,4‐tetrahydrobenzo[__b__][1,7]naphthyridines and 2,3,4,4a,5,6‐hexahydrobenzo[__c__][2,6] naphthyridines starting from anilines and 1‐benzyl‐4‐ethoxycarbonylpiperidin‐3‐one. The compounds were prepared in order to study their potent
## Abstract We developed a versatile synthesis of tetraaryl‐substituted benzo[1,2‐__b__:5,4‐__b__′]difurans (__m__‐BDFs) via a zinc‐mediated intramolecular double cyclization reaction of 4,6‐bis(phenylethynyl)‐1,3‐benzenediol, followed by a palladium‐catalyzed cross‐coupling reaction. In comparison
