Abstract
An original and efficient synthesis of quinolizidinones through a one-pot two-component cascade reaction of norlobelanine with in situ generated ketenes is reported. Functionalized fused azabicyclic scaffolds bearing multiple stereogenic centers were prepared with excellent diastereoselectivities. Mild optimized conditions involving a key "shuttle base" deprotonation strategy was applied to the synthesis, in a short sequence, of a constrained mimetic of the privileged H-bonded conformation of (-)-lobeline.

Abstract
Switchable tandem intramolecular aza-Michael/Michael and double aza-Michael reactions allow the oriented synthesis of highly functionalised cyclic skeletons. Conjugate addition of deactivated anilines triggers chemo- and stereo-divergent ring-closure reaction pathways with a striking selectivity depending on reaction conditions.

Abstract
Double cross-metathesis of 1,5-hexadiene with a variety of electron-deficient alkenes including the reluctant Weinreb acrylamide has been successfully accomplished. It was found that the process is quite general, and microwave irradiation effectively accelerates cross-coupling metathesis. This promotes a very versatile and high yielding methodology for the synthesis of symmetric Michael acceptors, which can be transformed into 2,5-disubstituted pyrrolidines through a sequential one-pot two-directional cross-metathesis/ring-closing double aza-Michael process.
