or 3‐aminoindazoles with 3‐ethoxycyclobutanones is presented. Diverse fused heterocyclesbenzo[4,5]‐imidazo[1,2‐a]pyrimidine and pyrimido[1,2‐b]‐indazole derivatives were obtained in moderate to high yields under mild conditions, the reaction mechanism of which was in sharp contrast to previous [3+3] annulation reaction of 3‐ethoxycyclobutanones.
A general two-stepsynthesis of substituted 3-aminoindazoles from 2-bromobenzonitriles involving a palladium-catalyzed arylation of benzophenone hydrazone followed by an acidic deprotection/cyclization sequence is described. This procedure offers a general and efficient alternative to the typical SNAr reaction of hydrazine with o-fluorobenzonitriles.
描述了由2-溴苯甲腈进行的一般两步合成取代的3-氨基吲唑,涉及钯催化的二苯甲酮的芳基化,然后进行酸性脱保护/环化序列。该方法为肼与邻氟苄腈的典型S N Ar反应提供了一种通用而有效的替代方法。

example for denitrogenative ring-opening of 3-aminoindazoles. This novel reactivity of 3-aminoindazoles enables the production of diverse aromatic nitrile-containing (hetero)arenes via C–H arylation of (hetero)arenes with wide subsrate scope under mild conditions.
