描述了3 {5}-氨基-5 {3}-(吡啶-2-基)-1 H-吡唑(I)的改进的合成,其提供了以克为单位的化合物。I与MeCN中的酰氯和异硫氰酸酯亲电试剂反应完全导致其氨基的进攻,从而生成N-(3- {pyrid-2-yl} -1 H -pyrazol-5-yl)酰胺和N-(3- {pyrid-2-yl} -1 H -pyrazol-5-yl)thiourea产品。这些是同时络合金属阳离子和阴离子的良好配体。但是我的治疗异氰酸酯在相同条件下反而会在吡唑环上产生侵蚀,使3-(吡啶-2-基)-5-氨基吡唑-1-羧酸酰胺成为唯一可分离的产物。通过1 H NMR和X射线晶体学证实了这些反应的不同区域化学。

transition-metal photosensitizer leads to efficient Dexter energy transfer and effective stereoinduction. The relative insensitivity of these organometallic chromophores toward ligand modification enables the optimization of this catalyst structure for high enantiomeric excess at catalyst loadings as much as 100-fold lower than the optimal conditions reported for analogous chiral organic photosensitizers.
