METHOD OF SYNTHESIS OF OPTICALLY ACTIVE DIMERIC COMPLEXES OF (1S,2S)-1,7,7-TRIMETHYL-2-[(DIALKYL-ALUMINA)OXY]- BICYCLO[2,2,1]HEPTANES Russian patent published in 2002 - IPC

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method of synthesis of optically active dimeric complexes of (1S, 2S)-1,7,7- trimethyl-2-[(dialkylalumina)oxy] -bicyclo[2.2.1]heptanes of the general formula (I) where R means C₂H₅, n-C₃H₇, i-C₄H₉ that involves interaction of (1S,2S)-1,7,7-trimethylbicyclo[2.2.1]heptane-2- one (camphor) with aluminum dialkylhydrides HAlR₂ where R is given above taken in the mole ratio = 10 : (10-12), respectively, in argon atmosphere, at the room temperature (~ 20 C), under normal pressure, in benzene medium for 0.5-1.5 h. New compounds can be used in fine organic and organometallic synthesis, in part, for synthesis of pure enantiomeric products with high optical yields. EFFECT: improved method of synthesis, enhanced purity, increased yield. 1 tbl
