Abstract
Abstract N-acyl (-CHO, -COMe, -COOMe, -COPh, -COCF 3 ) and N-sulfonyl (-SO 2 Me, -SO 2 Ph, -SO 2 ( p -tolyl) piperidines were synthesized and studied by cyclic voltammetry. Their anodic methoxylation was performed at various anodes (carbon rod, carbon felt, glassy carbon, Pt and PbO 2 ), in the presence of different electrolytes (But 4 NClO 4 , Et 4 NBF 4 and Et 4 NOTs), applying a current density of 20 mA cm −2 . Methoxylation on graphite with Et 4 NOTs favored the formation of α-monomethoxy products whereas in the presence of Et 4 NBF 4 , the α,α'-dimethoxy derivatives become predominant in selected cases.
