Practical one-pot synthesis of semicarbazone derivatives via semicarbazide, and evaluation of their antibacterial activity

New series of 2-(aryl or alkyl)-N-phenylhydrazine-1-carboxamides 1a-j were synthesized through one-pot reactions of aldehyde or ketones, hydrazine hydrate, and phenylisocyanate in MeOH. The structure of products was confirmed by Fourier transform infrared

Anodic cleavage of several ketone N-phenylsemicarbazones into methyl N-phenylcarbamate and the corresponding dimethyl acetals

Several ketone N-phenylsemicarbazones were electrooxidized in the presence of potassium iodide and a base using methanol as the solvent to give nearly commensurate amounts of methyl N-phenylcarbamate and the corresponding dimethyl acetals. Continuous evolution of gaseous nitrogen was observed from the anolyte during the electrooxidation. The reactions were carried out under very mild reaction conditions and are presumed to proceed through a four-electron oxidation process, in which the iodide ion plays an important role as an electron carrier.
