METHOD FOR PREPARING 1-(6,7-DIMETHOXY-1,2,3,4-TETRAHYDROISOQUINOLINE-2-YLAMINO)-1,2-DIHYDRO[60]FULLERENE Russian patent published in 2007 - IPC C07D217/24 

FIELD: organic chemistry, chelating agents, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of 1-(6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline-2-ylamino)-1,2-dihydro[60]fullerene of the formula (1) . Method involves interaction of fullerene-C₆₀ c salsolidine in the presence of Cp₂HfCl₂ as a catalyst in toluene medium, at temperature 140-160°C for 8-10 h. The yield of the end product is 62-83%. Invention provides the selective incorporation of one fragment in fullerene molecule to yield abovementioned compound of the formula (1) being synthesis of the latter is not described in literature. Synthesized compound can be used as chelating agent, sorbent and biologically active compound, and in creature of novel materials with desired electronic, magnetic and optical properties.

EFFECT: improved method of synthesis.
