Highly efficient and practical pyrrolidine-camphor-derived organocatalysts for the direct α-amination of aldehydes

Liu, Pang-Min,Magar, Dhananjay R.,Chen, Kwunmin

, p. 5705 - 5713 (2010)

A series of pyrrolidine-camphor-derived organocatalysts (1-4) were designed and synthesised. These organocatalysts were used for direct α-amination of aldehydes with dialkyl azodicarboxylates to give the desired α-aminated products in high chemical yields
