A double Mannich approach to the synthesis of substituted piperidones - Application to the synthesis of substituted E-ring analogues of methyllycaconitine
The double Mannich reaction of acyclic α,γ-substituted β-keto esters and bis(aminol) ethers gives substituted 3,5-substituted-4- piperidones with high levels of diastereoselectivity. These piperdiones can be easily transformed into substituted E-ring analogues of the delphinium alkaloid methyllycacotine.

Diastereoselective synthesis of substituted 4-piperidones and 4-piperidols using a double mannich reaction
A simple and efficient synthesis of polysubstituted 4-piperidones was achieved from the double Mannich reaction of β-keto esters and bisaminol ethers. The reaction is highly diastereoselective, as is the subsequent hydride reduction, to give polysubstituted 4-piperidols.
