This paper reports the synthesis of branched alkylene guanidines using microfluidic technologies. We describe the preparation of guanidine derivatives at lower temperatures, and with significantly less time than that required in the previously applic

The enzymatic reduction of levulinic acid by the chiral catalysts Chiralidon®-R and Chiralidon®-S which are commercially available superabsorbed alcohol dehydrogenases is described. The Chiralidon®-R/S reduces the levulinic acid to the (R,S)-4-hyd

High yield and selectivity in the intramolecular synthesis of the macrocyclic lactone oxacyclohexadecan-2-one were achieved via a straightforward biocatalytic synthesis utilising non-conventional solvents: supercritical carbon dioxide (scCO2), ethane

A highly automated 2-step method for measuring and correlating liquid–liquid equilibria (LLEs) is presented: In step 1, samples are prepared and measurements are performed; step 2 covers data extraction and correlation with thermodynamic models. Th

Previously, it could be demonstrated, that the monophasic, enzymatic reduction of aliphatic 2-ketones into the corresponding (R)-2-alcohols is an adequate and viable method as carried out in a cascade of two enzyme–membrane reactors (Leuchs, S.; Na

Biphasic reactions offer an attractive alternative for the utilisation of enzymes for conversion of hardly water soluble substrates. Especially, the alcohol dehydrogenase from Lactobacillus brevis was successfully used for the reductive synthesis of

Low solubility of starting materials and products in water and low enzyme utilisation are the two main obstacles for the production of enantiopure long-chain alcohols with alcohol dehydrogenases. A combination of techniques was used to overcome these

Continuous heat balance calorimetry allows determination of mixing efficiency by measurement of effective excess enthalpy of non-reactive streams. This can be normalised to the dimensionless goodness of mixing G with the experimentally independently
