Abstract
1,2-Dihydro-1,3,5-triazine compounds were synthesized through three sets of reactions of amidines with, respectively, paraformaldehyde, aldehydes and N-arylnitrones under different conditions. The catalysts used in these three reactions were Cu(OAc)2, ZnI2 and CuCl2·2H2O, respectively. Most of the substrates tested for these reactions provided the target products in moderate to good yields. In the reactions involving paraformaldehyde, Cu(OAc)2 also accelerated the release of formaldehyde from paraformaldehyde during the catalytic reaction process. In the case of the reactions involving nitrones, CuCl2·2H2O not only catalyzed the normal progress of the main reaction, but also promoted the reaction of nitrones to produce nitroso compounds and aldehydes.

Abstract
Polysubstituted tetrahydroquinolines were obtained in moderate to high yields (28% to 92%) and enantiomeric ratios (er 89:11 to 99:1) by a three-component Povarov reaction using a chiral phosphoric acid catalyst. Significantly, post-Povarov functional group interconversions allowed a rapid access to a library of 36 enantioenriched 4-aminotetrahydroquinoline derivatives featuring five points of diversity. Selected analogs were assayed for their ability to function as glucagon-like peptide-1 (GLP-1) secretagogues.

Abstract
Catalytic asymmetric Povarov protocols have undergone an explosive growth, especially in the last ten years, since the first example was published in 1996. The use of chiral Lewis and Brønsted acids and dual strategies based on their combination with catalysts acting by hydrogen bond formation, as well as covalent aminocatalysis, are reviewed. More recent variations such as the nitroso Povarov reaction and interrupted Povarov reactions as a route to chiral scaffolds other than tetrahydroquinolines are also discussed.

Abstract
A highly diastereoselective one-pot synthesis of the 1,3-diamino-2-alcohol unit bearing three continuous stereocenters is described. This method utilizes 2-oxyenamides as a novel type of building block for the rapid assembly of the 1,3-diamine scaffold containing an additional stereogenic oxygen functionality at the C2 position. A stereoselective preparation of the required (Z)-oxyenamides is reported as well.

Abstract
Over the last 16 years, chiral phosphoric acids (CPAs) have been shown to be excellent asymmetric catalysts, very effectively used in constructing chiral molecules with high enantiocontrol. In 2010, Ishihara et al. discovered that chiral metal phosphate complexes (or salts) could be found in substantial quantities, as contaminates, in some reported CPA-catalyzed reactions (Hatano, M.; Moriyama, K.; Maki, T.; Ishihara, K. Angew. Chem., Int. Ed. 2010, 49, 3823-3826). These metal phosphates were shown to actually catalyze the reactions in addition to CPAs. In this work, we have investigated in depth a reaction first reported to be catalyzed by CPAs based on a vaulted bis-phenanthrol (VAPOL) backbone. We have found that VAPOL metal phosphates were, in fact, superior catalysts for this reaction. Upon optimization, a wide substrate scope, low catalyst loading, and mild conditions could provide intermolecular imine amidation reactions producing chiral N,N'-aminal products in high yields and with excellent ee values (up to >99% yield, >99% ee).
