✦ Synopsis

quire the very unlikely cleavage of four bonds. A crossed condensation product is also irreconcilable with the 'H-N M R data, because, in contrast to 8, it would be centrosymmetric and would not exhibit splitting of the methyl and methylene signals of the ethyl side chains into two triplets and quadruplets, respectively. Furthermore, it can be assumed that the acid-catalyzed condensation of 6 first leads intramolecularly to 9b, from which only 8 can be formed.
