## Abstract The title compound **3f** is a novel isolable 1,10‐anthraquinone which is stabilized only by alkyl groups. Despite of the shielding of the __meso__ position **3f** reacts very fast with water and oxygen to give 3‐__tert__‐butyl‐1‐hydroxy‐5,8‐dimethyl‐9,10‐anthraquinone (**4f**).

## Abstract For the first time, tetracyclic compounds, namely, furo[2′,3′:3,4]cyclohepta[1,2‐b]indoles were synthesized by recyclization of __ortho__‐substituted aryldifurylmethanes containing __tert__‐butyl groups at C5 positions of the furan rings. It was shown that [2‐(benzoylamino)phenyl]bis(5‐
