leads to 2,7,12-trisubstituted truxenes. 5,10,15-Triarylated and trialkynylated truxenederivatives are obtained by the reaction of truxenone with aryl Grignard reagents or an alkynyllithium, followed by reduction of the tertiary alcohols with Et3SiH or BF3. syn-5,10,15-Triarylated derivatives were obtained by the base-catalyzed isomerization of the anti derivatives.

A regioselective oxidation of N-indan-4-yl-acetamide or N-(5,6,7,8-tetrahydronaphthalen-1-yl)acetamide with potassium permanganate followed by acidic hydrolysis gave 7-aminoindan-1-one or 8-aminotetral-1-one in good yield. The amino ketones were converted to the corresponding 7-haloindanone or the 8-halotetralone. Another method to prepare 7-haloindan-1-ones was completed by a cyclization of 3-chloro-1-(2-halophenyl)propan-1-one under Friedel-Crafts conditions to produce the product in gram quantity.
