, p. 936 - 940 (2017)
A ligand-based approach was applied to screen in silico a library of commercially available compounds, with the aim to find novel inhibitors of the HCV replication starting from the study of the viral NS3 helicase. Six structures were selected for evaluat

Upon incorporation of a noncovalent ion pair interaction, a new chiral ferrocenyl bisphosphorus ligand t-Bu-Wudaphos was developed. t-Bu-Wudaphos can be easily synthesized with very high diastereoselectivity as a highly air stable solid. The new ligand exhibited excellent reactivities and enantioselectivities in the asymmetric hydrogenation of α-methylene-γ-keto-carboxylic acids via an ion pair noncovalent interaction (up to >99% conversion, >99% ee).

Perkin condensation with subsequent intramolecular lactonisation as one pot synthesis of α-arylidine-γ-phenyl-Δ,β,γ- butenolides have been studied under microwave irradiation. The butenolides are cleaved to give keto acids, which are the precursors of pericarbonyl lactone lignans possessing variety of biological activities. Syntheses of butenolides have been carried out using pyridine as a catalyst under microwave conditions. The generality of this protocol has been demonstrated by synthesizing a variety of substituted butenolides in excellent yields, short reaction time and with good purity compared to those under classical thermal conditions. All the products have been characterized by their IR, 1H NMR and UV spectral values.

After decades of development, carbonylation reactions have become one of the most powerful tools in modern organic synthesis. However, the requirement of CO gas limits the applications of such reactions. Reported herein is a versatile and practical protocol for carbonylative reactions which rely on the cooperation of phenyl formate and nonaflate, and the generation of CO in situ. This protocol has a high functional-group tolerance and could be applied in carbonylations with C, N, and, O nucleophiles. The corresponding amides, alkynones, furanones, and aryl benzoates were synthesized in good yields.

A series of new 4-(aryl/heteroaryl-2-ylmethyl)- 6-phenyl-2-[3-(4- substituted piperazine-1-yl)propyl] pyridazin- 3(2H)-one derivatives were synthesized. The structures of the compounds were confirmed by IR, 1H NMR, and mass spectral data. All the compounds were evaluated for their cytotoxicity toward five human cancer cell lines of different origins viz; HeLa (Cervical), SKBR3 (Breast), HCT116 (Colon), A375 (Skin) & H1299 (Lung) at different concentrations and the IC50 values were determined. HCT116 and HeLa are the most sensitive against the compounds studied. One of them displayed moderate cytotoxicity against SKBR3. Majority of the compounds exhibited good to moderate activity.
