Ionic liquid promoted eco-friendly and efficient synthesis of six-membered N-polyheterocycles

Background: The synthesis of N-polyheterocycles by environmentally benign method is highly attractive but challenging proposition. New strategies have been developed for the preparation of polycyclic heterocycles in the last decades. In this review article, the synthesis of nitrogen containing six-membered polycyclic heterocyclic compounds is presented with the application of ionic liquids. This contribution focuses on the literature related to the total synthesis of six-membered N-polyheterocycles. Objective: Ionic liquids not only acted as environmentally benign reaction media but also as catalysts which afforded the very promising replacements of traditional molecular solvents in organic chemistry due to their stability, non-flammability, non-volatility and ease of recyclability. Ionic liquids are utilized in metal catalyzed reactions in place of organic solvents in the last years. It has attracted considerable attention in recent years. Ionic liquids acted as alternatives of organic solvents and these ILs are environment friendly. Conclusion: In the area of green chemistry ionic liquid assisted synthesis is a very promising technique which afforded a flexible platform for the formation of heterocycles. The influence of ILs on the development of efficient and new synthetic protocols over the last decade for the construction of N-polyheterocycles is featured in this review article. These synthetic strategies will continue to attract more attention and will find a wide range of applications in organic synthesis. In conclusion, ionic liquids assisted syntheses have become an efficient and powerful tool in organic chemistry quickly.

Synthesis and Antifungal Activity of Novel Furan-2,4-dione Derivatives Containing Substituted Phenylhydrazine Moiety

A series of novel 3-(2-(substituted phenyl)hydrazinylmethylidene)furan-2,4(3H,5H)-diones were designed and synthesized with ethyl 4-chloroacetoacetate as the starting material. Their structures were confirmed by FT-IR, 1H NMR, 13C NMR, EI-MS and elemental analysis. Bioassay data demonstrated that these compounds exhibited remarkable antifungal activity against Fusarium graminearum, Botrytis cinerea, Rhizoctonia cerealis and Colletotrichum capsici. Compound 3-(2-(4-bromophenyl)hydrazinylmethylidene)furan-2,4(3H,5H)-dione (5g) had excellent bioactivity against Botrytis cinerea with an EC50 value of 0.18 mug/mL – markedly lower than the 0.24 mug/mL of the commercial fungicide procymidone. The result revealed that introducing the halogenated phenylhydrazine at the 3-position of furan-2,4(3H, 5H)-dione was an effective way to design new tetronic acid derivatives as new fungicides. A series of novel furan-2,4-dione derivatives containing a substituted phenylhydrazine moiety were designed and synthesized. These compounds exhibited remarkable antifungal activity against Fusarium graminearum, Botrytis cinerea, Rhizoctonia cerealis and Colletotrichum capsici. Compound 5g showed significantly better bioactivity than the control fungicides.

Chiral imidazolidinone and proline-derived surface modifiers for the Pt-catalysed asymmetric hydrogenation of activated ketones

A series of imidazolidinone and proline derivatives have been synthesised and tested with regard to their suitability for the chiral modification of platinum used for the asymmetric hydrogenation of activated ketones. Hydrogenations of ketopantolactone (KPL), methyl benzoylformate (MBF) and trifluoroacetophenone (TFAP) performed at low hydrogen pressures (1 and 10 bar) were selected as test reactions. With some of these synthethic modifiers, encouraging levels of enantioselectivity were achieved (up to 73.5:26.5 e.r.) without optimisation of the reaction conditions. Moreover, performance enhancement of l-proline derived-modifiers, as a consequence of molecular editing with fluorine, was found to be significant (OH ? F, Deltaee up to 23%) contributing to the growing interest in modulating catalyst performance by fluorine introduction.
