Abstract : Objective: Many methods can be found in literature for the synthesis a Oxazines and Thiazines. Few are reported for one-pot multi component cyclo-condensation of an alkayane urea / Thiourea and Aldehyde to 2- amino-4H-1, 3-Oxazines or Thiazines. Different catalysts are reported like Trifluoro-acetic acid, glacial acetic acid under reflux condition Mandal and Co-workers have utilized perchloric acid (HClO4) supported on silica gel as catalyst under solvent free condition ytterbium trifluorate [Yb(OTF)3] plays role of Lewis acid. It is also used in several Diel’s-Alder cyclo-add

Abstract:
A library of regioisomeric monoterpene-based aminodiols was synthesised and applied as chiral catalysts in the addition of diethylzinc to benzaldehyde. The synthesis of the first type of aminodiols was achieved starting from (−)-8,9-dihydroperillaldehyde via reductive amination, followed by Boc protection and dihydroxylation with the OsO4/NMO system. Separation of formed stereoisomers resulted in a library of aminodiol diastereoisomers. The library of regioisomeric analogues was obtained starting from (−)-8,9-dihydroperillic alcohol, which was transformed into a mixture of allylic trichloroace

Abstract:
Pyrazoles have been focus of a large number of investigations in the design and synthesis of novel biologically active agents that show remarkable medicinal activities. Although pyrazoles have been studied for over a century as an important class of heterocyclic compounds, they still continue to attract considerable attention due to the wide range of medicinal activities they possess. Recent studies have shown that combination of a ferrocenyl unit with structural features of pyrazoles can lead to products with enhanced or/and unexpected biological activity since several ferrocene derivatives h

Abstract:
Crystallization-induced diastereoisomer transformation (CIDT) was successfully employed in the enantioselective synthesis of 2-alkyl-3-aryl-propan-1-amines. These products are seen as potentially useful building blocks in the field of asymmetric organic chemistry, notably for pharmaceutically relevant compounds. The procedure was based on a recently reported protocol for deracemization of dihydrocinnamic aldehydes in which enantiomerically enriched 1-(amino(phenyl)methyl)naphthalen-2-ol (Betti base) is employed as a resolving agent.

Abstract:
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
