resin in a traceless fashion is described. Azole substrates II are assembled in a one-pot condensation reaction of azoles and aldehydes with a resin-bound carbamyl chloride. Treatment of the azolyl-carbamate II with boron trifluoride etherate under thermal or microwave-assisted solvolysis conditions afforded 2-substituted azoles. [reaction: see text]
描述了一种使用聚苯乙烯-氨甲酰氯树脂以无痕方式制备2-取代的唑文库的新方法。唑和醛与树脂结合的氨基甲酰氯的一锅缩合反应组装了唑基化合物II。在热或微波辅助的溶剂分解条件下,用三氟化硼醚化物处理偶氮基氨基甲酸酯II,得到2-取代的唑。[反应:看文字]
