Online analytics provides insights into the progress of an ongoing reaction without the need for extensive sampling and offline anal. In this study, we investigated benchtop NMR as an online reaction monitoring tool for complex enzyme cascade reactions. Online NMR was used to monitor a two-step cascade beginning with an aromatic aldehyde and leading to an aromatic amino alc. as the final product, applying two different enzymes and a variety of co-substrates and intermediates. Benchtop NMR enabled the concentration of the reaction components to be detected in buffered systems in the single-digit mM range without using deuterated solvent. The concentrations determined via NMR were correlated with offline samples analyzed via uHPLC and displayed a good correlation between the two methods. In summary, benchtop NMR proved to be a sensitive, selective and reliable method for online reaction monitoring in (multi-step) biosynthesis. In future, online analytic systems such as the benchtop NMR devices described might not only enable direct monitoring of the reaction, but may also form the basis for self-regulation in biocatalytic reactions. The experimental process involved the reaction of 3-Hydroxybenzaldehyde(cas: 100-83-4Recommanded Product: 3-Hydroxybenzaldehyde)
3-Hydroxybenzaldehyde(cas: 100-83-4) can be used as a reactant along with ethyl acetoacetate and thiourea in the synthesis of corresponding dihydropyrimidine-2-thione (monastrol), using Yb(OTf)3 as a catalyst by Biginelli cyclocondensation reaction.Recommanded Product: 3-Hydroxybenzaldehyde
