The monofunctionalization of rccc-2,8,14,20-tetramethylresorc[4]arene (1) with (S)-(+)-10-camphorsulfonyl chloride led to a diastereomeric mixture of (+)-2a and (-)-2b, which were separated by HPLC. Permethylation of these compounds was [a

## Resolution of pentahelicene (4) was recently described['! We have now succeeded in the first allocation of absolute configuration to a helicene, namely to (+ )-( 4). The fundamental investigations of Mislow et al. ['], later confirmed by X-ray structure analysis[31, have shown that
