摘要
碱存在下,1-重氮-2,4-二羰基-5-炔基膦酸酯的环化提供新颖的3-膦酰基吡喃骈[3,2-c]吡唑-7-(1H)-酮衍生物,产率48%~99%.这种方法最显著的特点是反应条件温和,操作简单以及对不同底物具有优良的普适性.
Base-mediated cyclization of 1-diazo-2,4-dioxo-5-ynylphosphonate provided novel 3-phosphonyl pyrano[3,2-c] pyrazol-7（1H）-one derivatives in 48%-99% yields. Mild conditions, simple manipulation and functional group diversity are the salient features of this methodology.
