, p. 356 - 358 (2013)
A series of styryl substituted semicarbazides were synthesised by reaction of trans-styryl isocyanate, prepared by Curtius rearrangement of cinnamoyl azide, with acid hydrazides under microwave irradiation using a one-pot procedure. The effects of microwa

A series of monomeric and dimeric FeIII complexes bearing benzoic hydroxamates as O,O-chelates has been prepared and characterized by elemental analysis, IR spectroscopy, UV-Vis spectroscopy, electrospray ionization mass spectrometry (ESI-MS), cyclic voltammetry, EPR spectroscopy and for some examples by X-ray diffraction analysis. The stability of the synthesized complexes in pure water and seawater was monitored over 24 h by means of UV-Vis spectrometry. The ability to release iron from the synthesized model complexes has been investigated with algae growth experiments.

Carboxylating enoyl-thioester reductases (ECRs) are a recently discovered class of enzymes. They catalyze the highly efficient addition of CO2 to the double bond of α,β-unsaturated CoA-thioesters and serve two biological functions. In primary metabolism of many bacteria they produce ethylmalonyl-CoA during assimilation of the central metabolite acetyl-CoA. In secondary metabolism they provide distinct α-carboxyl-acyl-thioesters to vary the backbone of numerous polyketide natural products. Different ECRs were systematically assessed with a diverse library of potential substrates. We identified three active site residues that distinguish ECRs restricted to C4 and C5-enoyl-CoAs from highly promiscuous ECRs and successfully engineered a selected ECR as proof-of-principle. This study defines the molecular basis of ECR reactivity, allowing for predicting and manipulating a key reaction in natural product diversification.
