Access to 2,6-disubstituted piperidines: Control of the diastereoselectivity, scope, and limitations. applications to the stereoselective synthesis of (-)-solenopsine A and alkaloid (+)-241D

Abrunhosa-Thomas, Isabelle,Plas, Aurelie,Vogrig, Alexandre,Kandepedu, Nishanth,Chalard, Pierre,Troin, Yves

, p. 2511 - 2526 (2013/04/24)

Scope and limitations in the diastereoselective preparation of 2,6-cis or 2,6-trans disubstituted piperidines are described, through intramolecular reaction of chiral β′-carbamate-α,β-unsaturated ketone. This methodology has been applied to the total synthesis of a few well chosen examples, such as (-)-solenopsine A and alkaloid (+)-241D.
