A Mild and Selective Method for the Catalytic Hydrodeoxygenation of Cyanurate Activated Phenols in Multiphasic Continuous Flow

A low-energy, high-selectivity approach to the catalytic hydrodeoxygenation of phenols is reported using batch or continuous flow methods to react 3 equiv of phenol with cyanuric chloride then hydrogenolyzing the triarylcyanurate intermediate to give 3 equiv of deoxo aromatic. The use of cyanuric chloride compares favorably with existing activation methods, showing improved scalability, atom efficiency, and economics. The scope of both the activation and hydrogenolysis stages are explored using lignin-related phenols. Initial development has identified that continuous stir tank reactors (CSTRs) enable a multiphasic process for converting guaiacol to anisole and at steady state overcome the catalyst deactivation issues observed in batch, seemingly caused by the cyanurate byproduct. Green chemistry aspects and the potential for industrial adoption are discussed.

PROCESS FOR PREPARING AN ORTHO-SUBSTITUTED 5-HALOPHENOL AND A SYNTHESIS INTERMEDIATE THEREOF

A process for preparing a 5-halophenol, ortho-substituted by an electron-donating group, is described. Also described, is a process for preparing a sulphonic ester of an ortho-substituted phenol, which is the synthesis intermediate for the ortho-substituted 5-halophenol. The process for preparing a phenol ortho-substituted by an electron-donating group and protected in the form of a sulphonic ester can include reacting a phenol ortho-substituted by an electron-donating group with a sulphonylating agent in the presence of a Lewis acid. The process for preparing a 5-halophenol ortho-substituted by an electron-donating group can include a first step of preparing a phenol ortho-substituted by an electron-donating group and protected in the form of a sulphonic ester, as described above; a second step of halogenating the protected phenol intermediate obtained in the preceding step, in the position para to the electron-donating group; and a third step of deprotecting the sulphonic ester function to hydroxyl.

Synthesis and biological evaluation of a 2-aryl polyhydroxylated pyrrolidine alkaloid-based library

Inspired by polyhydroxylated pyrrolidine alkaloid natural products, a 18-membered library of 2-aryl polyhydroxylated pyrrolidines has been efficiently prepared in two or three synthetic steps from the known chiral cyclic nitrones with high yield and purity and excellent stereoselectivity. The inhibitory activity of all these compounds against various glycosidase enzymes was evaluated. Interestingly, 15 and 19 show better inhibitory activities than radicamine A (20) and B (18) against α-glucosidases. The IC50 values of 15 and 19 are 1.1 and 0.5 μM, respectively. In this study, we also discovered the substituent(s) on the aryl ring could affect the inhibition potency and selectivity against glycosidases.

Total synthesis of lamellarins D, L, and N

Total synthesis of cytotoxic marine alkaloids, lamellarins D, L, and N, has been achieved by using Hinsberg-type pyrrole synthesis and palladium-catalyzed Suzuki-Miyaura coupling of the 3,4-dihydroxypyrrole bistriflate 6 as the key reactions. The total yields of lamellarins D, L, and N from the common intermediate 6 are 54, 58, and 50%, respectively.

Facile preparation of organozinc bromides using electrogenerated highly reactive zinc and its use in cross-coupling reaction

Highly reactive zinc was readily prepared by electrolysis of a DMF solution containing pyrene as a mediator with a platinum cathode and a zinc anode. Preferential reduction of pyrene occurred to generate the corresponding radical anion, which reduced zinc ions generated from anodic dissolution to give zero valent zinc with high reactivity. The reactive zinc was successfully used for an efficient transformation of bromoalkanes into the corresponding organozinc bromides. Organozinc bromides obtained were further used successfully in Pd-catalyzed cross-coupling reaction with various aryl iodides and bromides.
