Kraevaya, Ol'Ga A.,Peregudov, Alexander S.,Troyanov, Sergey I.,Godovikov, Ivan,Fedorova, Natalya E.,Klimova, Regina R.,Sergeeva, Vasilina A.,Kameneva, Larisa V.,Ershova, Elizaveta S.,Martynenko, Vyacheslav M.,Claes, Sandra,Kushch, Alla A.,Kostyuk, Svetlana V.,Schols, Dominique,Shestakov, Alexander F.,Troshin, Pavel A.

We report an "inversed" Arbuzov reaction of the fullerene derivatives C60Ar5Cl with trialkyl phosphites P(OR)3 producing alkylated fullerene derivatives C60Ar5R (R = Me, Et, iPr, nBu) with almost quantitative yields. This reaction provides a convenient synthetic route for the preparation of a large variety of functionalized fullerene derivatives with tailored properties, e.g. water-soluble compounds demonstrating promising antiviral activities against HCMV, HSV1, HIV and several influenza virus strains.

The novel Lewis acid, lithium cobalt-bis-carbollide (1), in which the lithium ion is weakly coordinated to the Co(B9C2H11)2(1-) anion, is an effective, soluble catalyst for Mukaiyama-Michael reactions.

The hydrolysis of the meso-cyclopropane-1,2-dicarboxylates 1a-3a, 4, 5a, 6a, and 9, containing various substituents at C(3), and of the rac-3-phenylcyclopropane-1,2-dicarboxylates 7a, 8a, and 10 with pig liver esterase (PLE) is described.The stereoselectivity and absolute configurations of the products were determined.An interpretation of results was attempted on the basis of a recent active-site model for PLE.
