研究了偶氮二甲酸酯在新型氢键催化剂方酰胺3 j存在下催化1,3-二羰基化合物的不对称选择性α-肼化反应。在较低的催化剂负载量和温和的反应条件下,获得了较高的产率和对映选择性。
Catalytic enantioselective α-hydrazination of 1,3-dicarbonyl compounds with azodicarboxylates was investigated in the presence of our newly developed hydrogen bonding catalyst, squaramide 3j. High yields and high enantioselectivities were achieved with low catalyst loading under mild conditions.
