Abstract
We disclose herein the first enantioselective aza-Diels-Alder reaction of β-alkyl-substituted vinylketene silyl-O,O-acetals and imines furnishing a broad range of optically highly enriched 4-alkyl-substituted 2-piperidones. As a catalyst for this one-pot reaction we employed a chiral phosphoric acid which effects a vinylogous Mannich reaction directly followed by ring-closure to the lactam. Subsequent fully diastereoselective transformations including hydrogenation, enolate alkylation, and lactam alkylation/reduction processes converted the cycloadducts into various highly substituted piperidines of great utility for the synthesis of natural products and medicinally active compounds.

Abstract
The imino Diels-Alder reaction is an efficient method for the synthesis of aza-heterocycles. While different stereo- and enantioselective inverse-electron-demand imino Diels-Alder (IEDIDA) reactions have been reported before, IEDIDA reactions including electron-deficient dienes are unprecedented. The first enantioselective IEDIDA reaction between electron-poor chromone dienes and cyclic imines, catalyzed by zinc/binol complexes is described. The novel reaction provides a facile entry to a natural product inspired collection of ring-fused quinolizines including a potent modulator of mitosis.

Abstract
The asymmetric Povarov reaction with α-alkyl styrenes as dienophiles was catalyzed by an N,N'-dioxide L4-Sc(OTf)(3) complex. Enantiopure tetrahydroquinoline derivatives with a quaternary stereocenter at the C4 position were synthesized for the first time. A wide variety of α-alkyl styrenes and N-aryl aldimines were tolerated in the reaction, to give excellent diastereo- (up to 99:1 d.r.) and enantioselectivities (92 to >99% ee). In addition, the reaction could be performed on the gram scale without any loss of yield, diastereoselectivity, or enantioselectivity. An intermolecular hydrogen-shift reaction was found to be a side reaction, which offered a method to synthesize the corresponding quinoline derivatives with chiral quaternary sterocenters.
