| Title | One pot process for the arylation of beta-dicarbonyl compounds to produce a diverse range of complex bioactive natural products |
| Knowhow is available for | A transition-metal-free, chemo-selective, one pot process for the C- arylation of malonamide esters at room temperature with good yield |
| Summary | The alpha-arylation of active methylene carbonyl compounds has become a widely used method, which provides an easy access to important classes of biologically active natural/synthetic products. CSIR-NCL scientists have developed a one pot, room temperature process for the C-arylation of beta-dicarbonyl ester-amide compounds in presence of CsF and anhydrous polar organic solvent, optionally in presence of additives to obtain desired arylated dicarbonyl compounds with good yield. It is observed that the standardized arylation protocol could be applied for the generation of quaternary stereocenters, which are found in several important and useful molecules in pharmaceutical and medicinal applications, as well as in many natural products. Construction of such quaternary stereocenters is much more demanding and challenging task. The malonamide ester containing p-chloroaniline provides high yields at milder reaction condition. |
| Advantages | - The instant chemo-selective process is performed at room temperature and in one pot - The reaction to take place at room temperature in few hours, in mild conditions - Reaction used simple, further easily available reagents are employed and expensive transition metal catalyst is avoided - The instant arylation process is cost effective and industrially viable to obtain high yield of arylated dicarbonyl compounds |
