摘要

Tripinyltrioxanes of the general formula (I): <IMAGE> (I) in which the radicals Pin are either dextrorotatory (+) or laevorotatory (-) pinyl radicals; a process for the production of (I) by treatment of an enantiomeric mixture of (+)-3-formylpinane and (-)-3-formylpinane (II) with an acid in an organic solvent and fractional precipitation of the trimeric compound (I); and redissociation of (I) into the pure enantiomers (II) with a catalytic amount of an acid.
