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.
