Medium-Sized Cyclophanes. Part 31. Synthesis and Electrophilic Substitution of 8-Substituted Metacyclo(1,3)pyrenophanes

syn- and anti-2,11-Dithiametacyclo(1,3)pyrenophanes 15 have been obtained by coupling the corresponding 1,3-bis(bromomethyl)pyrene 11 and 1,3-bis(mercaptomethyl)benzenes 14 in ethanol under high-dilution conditions.Oxidation of the obtained thiametacyclophanes 15 with m-chloroperbenzoic acid afforded the corresponding syn- and anti-disulfones 18.Pyrolysis of the syn- and anti-disulfones 18 afforded exclusively the corresponding anti-metacyclo(1,3)pyrenophane 19 in 40-70percent yield along with the ring-cleavage product, 7-tert-butyl-1,3-dimethylpyrene 8.The nitration of 5,15-di-tert-butyl-8-methyl- 19b and 5,15-di-tert-butyl-8-methoxy-metacyclo(1,3)pyrenophane 19d with 1 mol equiv. of copper(II) nitrate in acetic anhydride solution exclusively occured on the more reactive pyrene ring to afford 14-nitro derivatives 21a and 21b in 83 and 86percent yield, respectively.On the other hand, the bromination of substrates 19 with bromide in methylene dichloride solution afforded 13-bromo derivatives 23 along with the transannular cyclization products 24 and 25.These different orientations for the electrophilic substitution are also discussed.
