P-Tolylsulfinylacetic acid

P-lactams Aceto(carbonyl)cyclopenta-dienyl-(triphenylphosphine)iron. Benzene-sulfenyl chloride. Chlorodicarbonylrho-dium(I) dimer. 2-Chloro-l-methylpyridin-ium iodide. Dimethylformamide-Thionyl chloride. Ketene bis(trimethylsilyl)-ketals.p-Tolylsulfinylacetic acid. Triphenyl-phosphine-Diethyl azodicarboxylate. Zinc. [Pg.587]

The racemic tetracyclic amine (3) can be coupled to ( )-(+)-p-tolylsulfinylacetic acid using the modified carbodi-imide reagent l-Cyclohexyl-3-(2-morpholinoethyl)carbodiimide Metho-p-toluenesulfonate to give the diastereomeric sulfinyl amides (4) and (5) (eq 2), which are readily separated by HPLC. ... [Pg.515]

Similarly, in a total synthesis of strychnine, the optical resolution was carried out by separation of the sulfinyl lactam diastere-omers (7) and (8), which were obtained from the heptacyclic indole alkaloid precursor (6) this was first transformed with (/ )-(+)-p-tolylsulfinylacetic acid into the corresponding sulfinyl amide and then converted to the diastereomeric lactams (7) and (8) by an intramolecular conjugate addition (eq 3). ... [Pg.515]
