afforded in up to 97% yields for more than 30 examples. The obtained products are potentially valuable in organic synthesis and drug discovery. This protocol featured with high efficiency, extensive functional group tolerance and mild reaction conditions. The one-step efficient construction of an anti-inflammatory agent confirms the practicability of this procedure.
已经开发了铑(III)与α- Cl酮催化的偶氮苯的[4 +1]环化反应。对于30多个实例,可以轻松以高达97%的收率获得3-Acyl-2 H-吲唑。所获得的产品在有机合成和药物开发中潜在有价值。该方案具有高效,广泛的官能团耐受性和温和的反应条件的特点。一步有效地构建抗炎剂,证实了该程序的实用性。
