Catalytic enantioselective alpha-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.
在我们新开发的氢键催化剂——螺二酰胺 3j 的存在下,研究了 1,3-二羰基化合物与重氮二甲酸酯的催化对映选择性α-酰腙化反应。在温和条件下,只需低催化剂负载量即可获得高产率和高对映选择性。
