A NOVEL ONE-POT SYNTHESIS OF SUBSTITUTED 4-t-BUTYLDIMETHYLSILYLOXY-THIAZOLES
Kopka, Ihor E.
, p. 3765 - 3768 (2007/10/02)
The reaction of 2-halo-acylimidazolides or halides with primary thioamides in base give 2-halo-N-acylthioamides, which cyclize to the substituted 4-thiazolones and are trapped as the novel 4-t-butyldimethylsilyloxythiazoles in fair to good yield.The 2-ary
