Process for the preparation of 6-[D(-)alpha-(4-ethyl-2,3-dioxopiperazin-1-ylcarbonylamino)-alpha-phenylacetamido]-penicillanic acid and intermediates useful in this process |
| abstract |
The 6-[D(-)-alpha(4-ethyl-2,3-dioxopiperazin-1-ylcarbonylamino)-alphaphenylacetamido]penicillanic acid and the salts thereof are prepared by synthetizing the novel intermediates, thioesters of D(-)-alpha-(4-ethyl-2,3-dioxopiperazin-1-ylcarbonylamino)-alpha-phenylacetic acid, with mercaptoheterocycles and by converting them into the desired compound by reaction with 6-amino-penicillanic acid. |
