| we studied D - penicillamine synthesis .first, penicillin G potassium dissolved in water. adding toluene and glacial acetic acid in turn and stirring at room temperature for a brief moment. adding the aniline under protect of nitrogen ,then heating reflux 5 h, we get D - penicillamine after one step. The product structure is affirmed by nuclear magnetic resonance (NMR) spectroscopy and optical rotation, and the yield of D - penicillamine is 64%. |
