The first asymmetric totalsynthesis of a new coccinellid alkaloid (−)-adalinine has been achieved, based on the construction of a 2-piperidone framework with an asymmetric quaternary center at the C-6 position, which was performed by Lewis acid-induced allylation of the cyclic N-acyl-N,O-acetal incorporating the chiral aminophenol auxiliary. This synthesis allowed the absolute stereostructure of natural
