By using the helix theory proposed by authors the rotatory direction of molecular can be deduced from configuration and conformation;conversely,the absolute configuration of molecules also can be deduced from the rotatory direction and value for some special biphenyl derivatives and similar compounds.

Several polysubstituted biphenyl compounds containing four skeletons were firstsynthesized from ellagic acid via a reduction with DIBAL-H.

Two polysubstituted biphenyl compounds were synthesized from ellagic acid.
