It is shown that treatment of stereoisomeric mixtures of styrenes with a catalytic amount of bis ( acetonitrile ) dichloropalladium (II) achieves smooth stereoisomerization of the (Z)-isomers to the (E)-isomers.

Very little supporting electrolyte or none at all is needed in flow electrochemistry. Recycling and waste problems are eliminated as cyclization products are obtained in a fast and clean process.
A modularly built bisubstrateinhibitor, the natural product pepticinnamin E (shown on the right) was sythesized for the first time. In the case of in vitro assays it inhibits the enzyme farnesyltransferase with respect to both the peptide substrate and farnesylpyrophosphate (KI = 30 and 8 μM, respectively). The inhibitoryactivity is decisively influenced by the central tripeptide unit and the absolute
