effectively carried out using hydrogenation over Pearlman's catalyst. This methodology allows the production of a broad range of unprecedented optically active 2,6-dialkyl-1,5-DACO, which could not be accessed by other methods.

Imine is one of the most versatile functional groups in chemistry and biochemistry fields. Although many biochemical reactions involve imine formation, the inherently unstable property of N‐alkyl‐α,β‐unsaturated imines still hindered their utilization in organic synthesis. In this article, we described that the N‐alkyl‐α,β‐unsaturated imines, which prepared from alkylamines and acrolein, could smoothly
