Rapid production of benzazole derivatives by a high-pressure and high-temperature water microflow chemical process

A high-pressure and high-temperature (HPHT) water microflow chemical process was utilized for the synthesis of benzazole derivatives. The current approach enables the extremely rapid production of various 2-arylbenzazoles including benzimidazoles, benzoxazoles, and benzthiazole in excellent yields.

Convenient synthesis of 2-aryl-benzimidazoles and 2,2′-diaryl-bisbenzimidazoles

2-Aryl-benzimidazoles and 2,2′-diaryl-5,5′-bisbenzimidazoles were synthesized conveniently by treating of trifluoromethyl aryl ketones with ortho-diamines in polar solvents with good to excellent yields. The reaction condition is mild and tolerant to most

Ionic-Liquid-Catalyzed Synthesis of Imines, Benzimidazoles, Benzothiazoles, Quinoxalines and Quinolines through C?N, C?S, and C?C Bond Formation

We report the tetramethyl ammonium hydroxide catalyzed oxidative coupling of amines and alcohols for the synthesis of imines under metal-free conditions by utilizing oxygen from air as the terminal oxidant. Under the same conditions, with ortho-phenylene diamines and 2-aminobenzenethiols the corresponding benzimidazoles and benzothiazoles were obtained. Quinoxalines were obtained from ortho-phenylene diamines and 1-phenylethane-1,2-diol, the conditions were then extended to the synthesis of quinoline building blocks by reaction of 2-amino benzyl alcohols either with 1-phenylethan-1-ol or acetophenone derivatives. The formation of C?N, C?S and C?C bonds was achieved under metal-free conditions. A broad range of amines (aromatic, aliphatic, cyclic and heteroaromatic) as well as benzylic alcohols including heteroaryl alcohols reacted smoothly and provided the desired products. The mild reaction conditions, commercially available catalyst, metal-free, good functional-group tolerance, broad range of products (imines, benzimidazoles, benzothiazoles, quinoxalines and quinolines) and applicability at gram scale reactions are the advantages of the present strategy.

METHOD FOR THE SYNTHESIS OF BENZAZOLE

PROBLEM TO BE SOLVED: To obtain a benzazole in a short reaction time with high yields. SOLUTION: A method for the synthesis of a benzazole includes a chemical reaction represented by the chemical reaction formula (1) to occur in subcritical water or supercritical water (X is NR6, O, or S. Y is H, OR7, halogen, or NR8R9. R1 to R9 are a C1-C20 aliphatic or aromatic substituent which may have O, N, S, B, Si, halogen, or P (two or more substituents of R1 to R6 may be coupled together, R8 and R9 may be coupled together, and two or more substituents of R1 to R9 may be the same) or H).
