An efficient lipase catalysed synthesis of optically enriched alpha-halogenated amides with concomitant optical enrichment of the starting alpha-haloesters is described. Candida antarctica lipase (CAL) was found to be a better catalyst over porcine pancreatic lipase (PPL) and Candida cylindracea lipase

The staurosporine derivative, N-benzoylstaurosporine (CGP 41 251; I), is a protein kinase C inhibitor that has been selected for phase I clinical evaluation in cancer patients. We have developed a selective and sensitive assay of the drug and three potential
Methyl tert-butyl ether (MTBE) is the most widely used oxygenate in gasoline blending and has become one of the world's most widespread groundwater and surface water pollutants. Alternative oxygenates to MTBE, namely ethyl tert-butyl ether (ETBE), tert-amyl ether (TAME) and
