  Nuclear fluorination of 2,4-diarylthiazoles with Accufluor®

  摘要：

  A series of 2,4-diphenylthiazole derivatives were synthesized and directly fluorinated at the 5-position by reaction with the N-F fluorinating reagent Accufluor (R). Although fluorination occurred selectively at the thiazole ring, it was always incomplete and thus yields for the novel fluorinated products were low to moderate (19-43%) following purification to remove starting material. Nonetheless, the target compounds were obtained in a convenient and straightforward manner. Selectfluor (R) was not as effective as Accufluor (R) as it gave a trace amount of the 5-chlorothiazole that was difficult to remove by chromatography. (c) 2006 Elsevier B.V. All rights reserved.

  A programmed synthesis of privileged arylthiazoles via sequential C–H couplings catalyzed by palladium or nickel catalysts has been accomplished. This versatile protocol can supply all possible arylthiazole substitution patterns (2-aryl, 4-aryl, 5-aryl, 2,4-diaryl, 2,5-diaryl, 4,5-diaryl, and 2,4,5-triaryl) from an unfunctionalized thiazole platform by 11 distinct synthetic routes.

  It adds up to 4! Thiophenes and thiazoles can be arylated in the 4‐ rather than the expected 5‐position in a new CH functionalization reaction (see scheme; TEMPO: 2,2,6,6‐tetramethylpiperidine‐N‐oxyl). The boronic acid proved to be the key to achieving the otherwise difficult C4 selectivity. The method was applied to a concise synthesis of a key pharmacological structure with potential for treatment
