Abstract:
N-Heterocyclic carbene (NHC), generated in situ from easily available N-heterocyclic imidazolium salt with air as terminal oxidant, has successfully been utilized as a cheap and efficient catalyst for one-pot aerobic oxidative synthesis of 2-arylbenzo[d]oxazoles, 2-substituted benzo[d]thiazoles, and 1,2-disubstituted benzo[d]imidazoles.

Abstract:
Six 1,3-oxazoles were synthetized in moderate to good yields by Van Leusen reaction in a pressure reactor. The methodology allowed to decrease the reaction times reported in the literature from hours to 20 min. In addition, preliminary qualitative recognition of cations with some synthetized oxazoles such as Hg2+, Ni2+, Zn2+, Ag+, Cu2+, Pb2+ was done and a “turn off” effect was observed with Ni2+. Finally, the 1,3-oxazoles could be of biological relevance because they are considered privileged nucleus in medicinal chemistry and therefore will be useful to obtain pharmacophoric hybrid molecules

Abstract:
The selective synthesis of oxazoles, alkylidene oxazoles, and 1,3-oxazines from N-propargyl carboxamides by choosing gold(III) or gold(I) catalysts and selecting terminal or internal alkynes as substrates is discussed. The mechanistic studies based on labeling experiments and intensive in situ NMR studies indicate an anti-oxyauration step and a proto-deauration with retention of the sterical arrangement at the double bond. The synthetic scope for gold(I) catalysts is very broad, allowing selective conversions to products with properties of chelate ligands, reactions of bromoarenes and the form

Abstract:
A new chemoselective method for the synthesis of 2-aryl-1,3-oxazoles by deoxygenation of the corresponding N-oxides has been developed. As the deoxygenation reagent, a previously unknown complex of collidine with phosphorus trichloride in a 2:1 ratio has been used. The developed method enabled the preparation of a wide range of 2-aryl-1,3-oxazoles comprising various functional groups in good yields. The advantage of this reagent is its tolerance to nitro, methyl, hydroxyl, formyl, and acetyl groups, and double bonds. Due to chemoselectivity and availability of reagents, the method may be used

Abstract:
The development of novel targeted therapeutics for the treatment of cancer remains difficult due to the complex nature of the disease itself as well as the challenges associated with the synthesis of these therapeutics. Impediments to the discovery of novel drug candidates include lack of available starting materials and access to well-developed syntheses which are both convenient and economically feasible. Semicarbazides, for instance, are a critical synthon for the manufacture of numerous biologically important molecules. Historically, convenient methods for the synthesis of semicarbazides a
