Since the discovery that FK-506 promotes neurite outgrowth, considerable attention has been focused on the development of potent non-immunosuppressive ligands for FK-506 binding proteins (FKBPs). Such neuroimmunophilin agents have been reported to show neuroregenerative activity in a variety of cell and animal models including neurite outgrowth, age-related cognitive decline, Parkinson’s disease, peripheral nerve injury, optic nerve degeneration, and diabetic neuropathy. A unique series of tetracyclic aza-amides that have been shown to be potent FKBP-12 rotamase inhibitors were designed and synthesized. The structure-activity relationships established in this study have demonstrated diverse structural modifications that result in potent rotamase inhibitory activity. This study involved multiple reactions and reactants, such as 2-(2,3-Dichlorophenyl)-2-oxoacetic acid (cas: 93942-57-5Name: 2-(2,3-Dichlorophenyl)-2-oxoacetic acid).

Greening Oxidation Catalysis: Water as a Solvent for Efficient Alkene Epoxidation over a Titanosilicate/H₂O₂ System was written by Yu, Yunkai;Fang, Nan;Chen, Zhen;Liu, Dongxu;Liu, Yueming;He, Mingyuan.

Herein, we disclose the application of water (H₂O) solvent in titanosilicate-catalyzed epoxidation of alkenes. A highly efficient H₂O-solvent propylene epoxidation system (Ti-MWW/H₂O/H₂O₂/propylene/K⁺) was achieved, possessing high activity, selectivity, and stability. Our investigation shows that this excellent catalytic performance is ascribed to the structure variation of H₂O induced by K⁺. The superior H₂O structure is the one that donates two and accepts one hydrogen bond (HB), which is known as the “DDA” H₂O structure. The current report benefits sustainable applications in titanosilicate-catalyzed alkene epoxidation and conforms to the principles of green chem.

And the article was included in Advanced Synthesis & Catalysis in 2020.Name: Ethyl 4-chloro-3-oxobutanoate The following contents are mentioned in the article:

Biocatalytic redox reactions regularly depend on expensive cofactors that require recycling. For continuous conversions in flow chem., this is often an obstacle since the cofactor is washed away. Here, we present a quasi-stationary recycling system for NADP utilizing an immobilized alc. dehydrogenase. Four model substrates were reduced with high enantioselectivity as a proof of concept. The two-phase system enables continuous production as well as quick substrate changes. This setup may serve as a general cofactor regeneration module for continuous biocatalytic devices employing (co-)substrates being miscible in organic solvent. The system resulted in space-time yields up to 117 g L^-1 h^-1 and total turnover numbers for NADP higher than 12,000 mol/mol are possible.
