Process for converting optically active l-N-(2-amino-2-phenethyl)-2-methoxyethylamine to the corresponding dl-derivative

There is provided a process for racemizing an undesirable, optically active compound for conversion to levamisole, namely, l-N-(2-amino-2-phenethyl)-2-methoxyethylamine, by converting the latter to optically active l-(2-methoxyethyl)-4-phenyl-2-imidazolidone, which is next converted to the corresponding optically inactive imidazolidone derivative, which derivative is hydrolyzed to the optically inactive racemate, dl-N-(2-amino-2-phenethyl)-2-methoxyethylamine. The latter can be resolved to obtain the d and l components of the racemate, the d component being utilized directly in levamisole synthesis and the l component being again subjected to the above procedure.

Chiral rhodium-diphosphine catalyst capable of catalytic reduction of a tetramisole precursor to give a significant excess of the desired S-(-)isomer, levamisole

A soluble, chiral, rhodium-containing catalyst which permits the catalytic reduction of prochiral 3-acyl-1-(2-alkoxyethyl)-4-phenyl-2-imidazolinones to chiral 3-acylimidazolidinones with a substantial excess of the desired S optical isomer. The 3-acylimidazolidinones may in turn be substantially converted to levamisole, and S isomer of tetramisole. The resolution of tetramisole to remove the R isomer is thus avoided.

Intermediates for synthesis of tetramisole, levamisole and their derivatives

A process for the manufacture of 1-(2-alkoxyethyl)-4-phenyl-4-imidazolin-2-ones, 1-(2-alkoxyethyl)-4-phenyl-2-imidazolidones, 1-(2-alkoxyethyl)-4-phenyl-imidazolidine-2-thiones, certain of the corresponding 1-(2-hydroxyethyl) derivatives and their 3-acylated derivatives, and certain related compounds which are all useful as intermediates in a new process for the manufacture of tetramisole, dl-2,3,5,6-tetrahydro-6-phenylimidazo-[2,1-b]thiazole, and its derivatives. The compound tetramisole is useful as an anthelmintic.
