Abstract
Electrolysis of 3-arylthiomethyl-Δ³-cephems possessing various substituents on the arylthio moiety undergo chemoselective and product-selective electrooxidation to give several different products. These include isomeric mixtures of the corresponding methoxylated cephems, a bis[(Δ³-cephem-3-yl)methyl]disulfide or a 3-dimethoxymethyl-Δ³-cephem. The selectivity of the oxidation is highly dependent on the nature of the substituents on the arylthio moiety which suggests that both steric and electronic effects play an important role in the electrooxidation of 3-arylthiomethyl-Δ³-cephems.

moiety at the C-3 position of cephalosporin derivatives, has been
used as an orally active drug. Its precursor, 3-methoxymethyl-Δ³-cephem
was prepared by methoxylation of the correspond-ing 3-acetoxymethyl-Δ³-cephem
derivative using CaCl2 in aq MeOH, see:
