  Efficient synthesis of 5′-fluoroalkoxythiazoles via α-bromo-α-fluoroalkoxyacetophenones Hantzsch type cyclization with thioureas or thioamides

  摘要：

  Novel alpha-fluoroalkoxyacetophenones were synthesized by addition of the readily available 2,2-dimethoxy-2-phenylethanol to fluoroolefins. alpha-Bromination yielded alpha-bromo-alpha-fluoroalkoxyacetophenones, which on treatment with thioureas or thioamides gave thiazoles with fluoroalkoxy groups at the 5'-position by the Hantzsch-type cyclization. This provides a versatile methodology for the construction of heterocycles from aliphatic fluoroalkoxy containing building blocks. (C) 2012 Elsevier B.V. All rights reserved.

  2-Fluoroalkoxyenaminones were synthesized from alpha-fluoroalkoxyacetophenones and dimethylformamide dimethylacetal in almost quantitative yields. These compounds are promising aliphatic precursors for fluoroalkoxy containing heterocycles construction that was proved by reactions with hydrazine, hydroxylamine and amidines yielding corresponding pyrazoles, isoxazoles and pyrimidines.
