Abstract:
Various 4-aminotetrahydropyridinylidene salts were treated with aldehydes in an alkaline medium. Their conversion to 5-substituted β-hydroxyketones in a one-step reaction succeeded only with an aliphatic aldehyde. Instead, aromatic aldehydes gave 5-substituted β-aminoketones or a single δ-diketone. The new compounds were characterized using spectroscopic methods and a single crystal structure analysis. Some of them showed anticancer and antibacterial properties.

Abstract:
Efficient one-pot Ugi–Smiles couplings are reported for the use of furyl-substituted aldehyde components. In the presence of these heterocyclic aldehydes, reactions tolerated variations in amine components and led to either isolated N-arylamide Ugi–Smiles adducts or N-arylepoxyisoindolines, products of tandem Ugi–Smiles Diels–Alder cyclizations, in moderate yields. A thienyl-substituted aldehyde was also a competent component for Ugi–Smiles adduct formation.

Abstract:
S-triazines are photosynthetic inhibitors. They have been substituted with ω-aminoundecanoic acid. The coupling products have been transformed into triazine aldehydes. These compounds displace radioactive terbutryn and have inhibitory effects on photosynthesis in plants and bacteria. Triazine aldehydes were shown to be effective substrates for bacterial luciferase. A competitive assay between photosystem-II-herbicides and aldehyde-labeled triazines is discussed.

Abstract:
Novel azole adducts were produced by reaction of azoles and 2-acyloxyaryl aldehydes. The mechanism of the reaction involves attack by the azole at the carbonyl group and transfer of the acyl group to form an azole-substituted benzylic ester. 2-Acyloxyaryl ketones did not undergo an analogous reaction. An aminal was formed rather than an azole-substituted benzylic carbonate when a 2-aryl aldehyde carbonate was used as substrate.

The first half of this dissertation describes the synthesis and biological activities of a series of amino aldehydes; which were derivatives of the basic amino acids, arginine, lysine and ornithine. The synthesis of the amino aldehydes was complicated by the difficulty of producing an intermediate oxidation state (the aldehyde) in the presence of two other functional groups (the α-amino, and the side chain functionality). The amino aldehydes were of biological interest due to the fact that they were inhibitors of the proteolytic enzymes called kallikreins. The kallikreins are known to be invol
