โฆ Synopsis
Abstract
Five new barrelโshaped macrobicyclic compounds capable of complexation with anions have been prepared. Intermediate triamines were prepared in oneโstep using a triple Mitsonobu reaction, thereby shortening the overall synthetic sequence. A previously prepared benzeneโbridged hexaazamacrocycle was prepared in only fourโsteps.

## Abstract In this paper we report on the photochemistry of Dewar benzenes bridged at the 1,4โ and 5,6โpositions and substituted at the 2,3โpositions. It was found that simple alkyl substitution leads to prismanes only to a minor extent. Introduction of phenyl groups into the 2โ or 2,3โpositions g
