5-acyl-4-alkyl-2-aminooxazoles

TABLE 1.48. 5-ACYL-4-ALKYL-2-AMINOOXAZOLES FROM FRIEDEI CRAFTS REACTIONS OF 4-ALKYI 2-AMINOOXAZOlES ... [Pg.139]

The 2- and 5-aminooxazoles afford normal acyl and arenesulfonyl derivatives but attempts to diazotize the amino group have been unsuccessful. Oxazoles with a free amino group in position 4 are unknown, as are hydroxyoxazoles. 2-Methylthiooxazoles are produced when oxazole-2-thiones are methylated in alkaline solution. For the alkylation and benzoylation of benzoxazole-2-thione, see Section 4.18.3.1.4(ii). [Pg.216]
