SYNTHESIS OF PIPERAZINOMYCIN, A NOVEL ANTIFUNGAL ANTIBIOTIC

Piperazinomycin, a novel antifungal antibiotic, has been synthesized from tetrabromotyrosyltyrosine, whose oxidation with thallium trinitrate (TTN) leads to the formation of a strained 14-membered ring similar to that of piperazinomycin as a key step.

ATTOGRAM-LEVEL DETECTION AND RELATIVE RESPONSE OF STRONG ELECTROPHORES BY GAS CHROMATOGRAPHY WITH ELECTRON CAPTURE DETECTION.

The responses as peak areas of some divergent compounds, most of which are strong electron absorbers, are measured by gas chromatography with electron capture detection (GC-ECD). The most sensitive compounds are derivatized lodothyronines, which are essentially 20-fold more sensitive than lindane. N,N-Dipentafluorobenzoylpentafluoroaniline, a somewhat less sensitive but more volatile substance, was selected for determination of a detection limit. The value was 90 ag(1. 6 multiplied by 10** minus **1**9 mol), largely due to an anomalous increase in its response at the trace level. This increases the reported sensitivity of GC-ECD by 100-fold.
