“…Literature suggests that the alteration of pH may ultimately alter the bioflocculant charge status and surface characteristics of suspended particles consequently changing the flocculating ability (Zhang et al. ). This variation in the pH requirement of the reaction mixture may be due to the bioflocculants showing different electric states at different pH values and hence affecting the flocculation capability of the bioflocculants for the kaolin particles (Pan et al.…”

Chemical flocculants are generally used in drinking water and wastewater treatment due to their efficacy and cost effectiveness. However, the question of their toxicity to human health and environmental pollution has been a major concern. In this article, we review the application of some chemical flocculants utilized in water treatment, and bioflocculants as a potential alternative to these chemical flocculants. To the best of our knowledge, there is no report in the literature that provides an up‐to‐date review of the relevant literature on both chemical flocculants and bioflocculants in one paper. As a result, this review paper comprehensively discussed the various chemical flocculants used in water treatment, including their advantages and disadvantages. It also gave insights into bioflocculants production, challenges, various factors influencing their flocculating efficiency and their industrial applications, as well as future research directions including improvement of bioflocculants yields and flocculating activity, and production of cation‐independent bioflocculants. The molecular biology and synthesis of bioflocculants are also discussed.

“…Notwithstanding, several methods to stereoinvertively introduce nitrogen atoms from alcohol 5 that do not involve sodium azide, such as the Mitsunobu reactions and Merck’s method, , have been reported and investigated. However, the Mitsunobu reaction, in which phthalimide was used as the nucleophile, could not be reproduced in our laboratory, and the desired product was obtained in low yield (Scheme S2).…”

Stereoinvertive deoxyamination involving Bose−Mitsunobu azidation and the Staudinger reaction, which proceeds under mild conditions in the presence of a neighboring group, was successfully applied for the synthesis of edoxaban. The one-pot process allowed access to key intermediates of edoxaban without isolating azide intermediates. Furthermore, the efficiency of the Bose−Mitsunobu azidation was dramatically improved by changing the substituent on the neighboring group from the Boc group to a thiazole carbonyl unit.
