METHOD FOR PRODUCTIO OF STEREOISOMERIC ISO-PROPYL 5'-ALKYL-1'N-PYRROLIDINO[3',4':1,9](C60-IH)[5,6]FULLERENE-2'-CARBOXYLATES MIXTURE Russian patent published in 2017 - IPC C07D207/16

Abstract RU 2629754 C1

FIELD: chemistry.

SUBSTANCE: method for production of a mixture of stereoisomeric isopropyl 5'-alkyl-1'H-pyrrolidino[3',4':1,9](C_60-I_h)[5,6]fullerene-2'-carboxylates of the general formula

is characterized by C60-fullerene reaction with methyl isocyanoacetate of the formulaMeO₂CCH₂N⁺≡C^- in chlorobenzene under the action of the Ti(OiPr)4 catalyst in the presence of RMgBr (where R = Et, Bu, i-Pr), taken in the molar ratioofC₆₀: isocyanoacetate:Ti(O/Pr)₄:RMgBr = 1:(2-6):(1-5):(6-10), at a temperature of 100°C for 5-30 minutes.

EFFECT: improved method.
