The absolute configuration of novel chiral molecules , optically active multifunctional carbon compounds, has been determined for the first time by X-ray analysis after successful conversion into crystalline derivatives. We have recently reported the synthesis 1 and resolution 2,3 of multifunctiona
## 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
