Method for synthesizing 2 - amino -5 - arylthiazole

The present invention discloses a synthetic method of 2-amino-5-arylthiazole. The method is as below: dropwise adding an organometallic reagent into raw materials of 2,6-dibromo anisole and tetrahydrofuran under nitrogen protection, and stirring at room temperature or low temperature for 2 h until the materials disappear; dropwise adding a tetrahydrofuran solution containing N- methyl-N-methoxy-chloro acetamide and insulating until the disappearance of a TLC indicated intermediate; dropwise adding saturated ammonium chloride solution, separating and extracting the aqueous phase with ethyl acetate; combining the organic phases, and evaporating the solvents to obtain 2'-chloro-3-bromo-2-methoxyacetophenone; adding 2'-chloro-3-bromo-2-methoxyacetophenone, thiourea and ethanol to a reaction flask, and heating at reflux; cooling, adding into an aqueous solution of sodium bicarbonate; and filtering and drying to obtain 2-amino-5-(2'-methoxy-3'-bromo)phenyl-thiazole. The method is easy, realizes one-step synthesis of 2'-chloro-3-bromo-2-methoxyacetophenone intermediate, and utilizes the intermediate for high yield synthesis of 2-amino-5-(3'-bromo-2'-methoxy) phenylthiazole.

A tyrosine-derived benzofuranone related to diazonamide A.

[formula: see text] Cyclization of 8 with PPA followed by MCPBA oxidation affords the benzofuranone 10. Treatment with a chiral chloroformate in the presence of DMAP affords the target benzofuranone 13 via an enol ester 12.
