An efficientone-pot three-component synthesis of a series of α-hydrazino amides, obtained in high diastereoselectivity and yield, was realized starting from cyclic ketones, hydrazides, and isocyanides in the presence of 10 mol % p-TsOH in ethanol at room temperature. The synthetic protocol was optimized and the observed diastereoselectivity was measured using 1H NMR spectroscopy.
在室温下,在乙醇中存在10 mol%对-TsOH的情况下,从环状酮,酰肼和异氰酸酯开始,实现了以高非对映选择性和高收率获得的一系列高效α-肼基酰胺的单锅三组分合成方法。温度。优化了合成方案,并使用1 H NMR光谱测量了观察到的非对映选择性。
