Activation with ytterbium triflate of these azadienes affords dimeric structures through aza-Diels-Alder reaction, where the alkene double bond of 1-azadienes also adopts the role of dienophile. An asymmetric synthesis of functionalised 1,4,5,6-tetrahydropyridine compounds derived from a-amino acids using an optically active enamine is reported.
