Abstract
The one-pot nucleophilic ring-opening reaction of oligoethylene glycol macrocyclic sulfates provides an efficient strategy for the monofunctionalization of oligoethylene glycols without protecting or activating group manipulation. In this strategy, the hydrolysis process is generally promoted by sulfuric acid, which is hazardous, difficult to handle, environmentally unfriendly, and unfit for industrial operation. Here, we explored a convenient handling solid acid, Amberlyst-15, as a replacement for sulfuric acid to accomplish the hydrolysis of sulfate salt intermediates. With this method, 18 valuable oligoethylene glycol derivatives were prepared with high efficiency, and gram-scale applicability of this method has been successfully demonstrated to afford a clickable oligoethylene glycol derivative 1b and a valuable building block 1g for F-19 magnetic resonance imaging traceable biomaterial construction.

Abstract
Regioselective functionalization of gem-difluoroalkenes enables convergent late-stage access to fluorinated functional groups, though most functionalization reactions proceed through defluorinative functionalization processes that deliver mono-fluorovinyl products. In contrast, fewer reactions undergo net hydrofunctionalization to generate difluorinated products. Herein, we report a photocatalytic hydrothiolation of gem-difluoroalkenes that enables access to a broad spectrum of α,α-difluoroalkylthioethers. Notably, the reaction successfully couples nonactivated substrates, which expands the scope of accessible molecules relative to previously reported reactions involving organo- or photocatalytic strategies. Further, this reaction successfully couples biologically relevant molecules under aqueous conditions, highlighting potential applications in both late-stage and biorthogonal functionalizations.

Abstract
Raspberry ketone (RK), the main aroma compound of raspberry fruit, has applications in cosmetics, food industry, and pharmaceutics. In this study, we biosynthesized RK via the catalytic reduction of 4-hydroxybenzylidenacetone using a whole-cell biocatalyst. Reductase RiRZS1 from Rubus idaeus and glucose dehydrogenase SyGDH from Thermoplasma acidophilum were expressed in Escherichia coli to regenerate NADPH for the whole-cell catalytic reaction. Following the optimization of balancing the coexpression of two enzymes in pRSFDuet-1, we obtained 9.89 g/L RK with a conversion rate of 98% and a space-time yield of 4.94 g/(L·h). The optimum conditions are 40 °C, pH 5.5, and a molar ratio of substrate to auxiliary substrate of 1:2.5. Our study findings provide a promising method of biosynthesizing RK.

Abstract
Food additives and colorants are extensively used in the food industry to improve food quality and safety during processing, storage and packing. Sourcing of these molecules is predominately through three means: extraction from natural sources, chemical synthesis, and bio-production, with the first two being the most utilized. However, growing demands for sustainability, safety and "natural" products have renewed interest in using bio-based production methods. Likewise, the move to more cultured foods and meat alternatives requires the production of new additives and colorants. The production of bio-based food additives and colorants is an interdisciplinary research endeavor and represents a growing trend in future food. To highlight the potential of microbial hosts for food additive and colorant production, we focus on current advances for example molecules based on their utilization stage and bio-production yield as follows: (I) approved and industrially produced with high titers; (II) approved and produced with decent titers (in the g/L range), but requiring further engineering to reduce production costs; (III) approved and produced with very early stage titers (in the mg/L range); and (IV) new/potential candidates that have not been approved but can be sourced through microbes. Promising approaches, as well as current challenges and future directions will also be thoroughly discussed for the bioproduction of these food additives and colorants.
