METHOD FOR COMBINED SYNTHESIS OF 1'-(3-1H-INDOLEMETHYL)-1'-ETHYLFORMYL-(C-I)[5,6]FULLERO[2'3':1,9]CYCLOPROPANE AND 1'a-(3-1H-INDOLEMETHYL)1'a-ETHYLFORMYL-1'a-CARBA-1'(2')a-HOMO(C-I)[5,6]FULLERENE Russian patent published in 2012 - IPC C07D209/18

Abstract RU 2440340 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for combined synthesis of a novel 1'-(3-1H-indolemethyl)-1'-ethylformyl-(C₆₀-1_h)[5,6]fullero[2',3':1,9]cyclopropane and 1'a-(3-1H-indolemethyl)-1'a-ethylformyl-1'a-carba-1'(2')a-homo(C₆₀-1_h)[5,6]fullerene of general formula (1) and (2) : involving reaction of C₆₀-fullerene with ethyl 2-(3-1H-indolemethyl)-2-diazoacetate in o-dichlorobenzene in the presence of a three-component catalyst {Pd(acac)₂:2PPh₃:4Et₃Al}, taken in molar ratio C₆₀:ethyl 2-(3-1H-indolemethyl)-2-diazoacetate:Pd(acac)₂ : PPh₃ : Et₃Al=0.01:(0.01-0.10) : (0.0015-0.0025):(0.003-0.005):(0.006-0.01), preferably 0.01:0.05:0.002:0.004:0.008, at temperature 80°C for 0.5-1.5 hours.

EFFECT: improved method.
