Metacyclophanes and Related Compounds. 24. Preparation and Reaction of Trimethyl- and Tetramethylmetacyclophane

8,16,24,32-Tetramethyl- and 8,16,24-trimethylmetacyclophane (9 and 10) were prepared by using the tert-butyl group as a positional protective group.Friedel-Crafts acylation of 9 and 10 afforded the corresponding ketones, 12 and 13, respect
