A green 1,4-addition isocyanide-based three-component reaction was developed to synthesize chromanones via a facile, mild, and efficient one-pot protocol without a metal catalyst. The 1,4-addition of isocyanides occurred at the C-2 position of chromones instead of the Schiff base in neat water. The hydrogen bond can dictate the stereo-outcome of olefins and provided an effective method for the diastereomer-selective synthesis of this type of chromanone. The novel green synthetic protocol allowed the quick synthesis of complex chromanones in an environmentally friendly manner.

In this report, the authors chem. synthesized kinsenoside, goodyeroside A and their analogs with glycan variation, chirality inversion at chiral center(s), and bioisosteric replacement of lactone with lactam. Among these compounds, goodyeroside A and its mannosyl counterpart III demonstrated superior anti-inflammatory efficacy. Furthermore, goodyeroside A was found to suppress inflammation through inhibiting the NF-κB signal pathway effectively. The structure-activity relationship is also explored for further development of more promising kinsenoside analogs as drug candidates.

This paper presents heuristics for the integration of fermentation with the appropriate crystallization based in-situ product recovery (ISPR) technique. Here techniques, such as co-crystallization (CC), evaporative crystallization (EC), template induced crystallization (TIC), cooling crystallization (ClC) and electrochem. induced crystallization (EIC), that were recently developed or applied to fermentations were evaluated. For this purpose, the operating windows of fermentation and crystallization of the top-twelve platform chems. as identified by the US Department of Energy were extracted from literature and processed. The results show that in principle all mols. can be crystallized and confirm that different classes of platform chems. require different crystallization techniques. Finally, the results show that intensified crystallization, by means of utilizing external fields (EIC) or tunable solid state properties (CC), seems to be a very feasible ISPR technique.
