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.

Walser, Paula,Renold, Peter,N'Goka, Victor,Hosseinzadeh, Fatemeh,Tamm, Christoph
, p. 1941 - 1952 (2007/10/02)
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.
SYNTHESIS OF 4-SUBSTITUTED GLUTARIMIDES BY FREE RADICAL ADDITION OF IODOACETAMIDE TO α,β-UNSATURATED ESTERS
Sacripante, Guerino,Tan, Charles,Just, George
, p. 5643 - 5646 (2007/10/02)
Free radical addition of either methyl bromoacetate or iodoacetamide to an α,β-unsaturated ester gave the 4-substituted glutarate or glutarimide respectively, whereas the radical cyclisation of N-bromoacetyl crotonamide gave the 2-substituted succinimide.
