PANKAJ R CHAUDHARI NANDU B BHISE GIRIJ P SINGH VARADARAJ BHAT GAUTHAM G SHENOY
Selective α-aminoxylation was achieved on corresponding aldehyde with great enantiomeric excess to get intermediate (5) using catalytic amount of low cost proline. The oxazolidinone ring was then constructed on common intermediate (5) which was then further converted to Oxazolidinone class compounds like Sutezolid and Eperezolid.

Comparison of the frequency dependent rotational friction among three different solvent systems considered – normal liquid (ethanol), deep eutectic solvent (acetamide/LiBr) and ionic liquid ([BMIM][BF6]). Note the high frequency friction values for these solvents are very similar, although their zero frequency values differ quite considerably because of widely different viscosities.

Macro-RAFT agents were successfully synthesized in high yield by reacting S-dodecyl-S′-(α,α′-dimethyl-α″-acetic acid) tritiocarbonate (DDMAT) (R-2) with polyethylene glycols (Mn: 2000 Da and 8000 Da, respectively). Subsequently, the monomers methyl methacrylate (MMA) and N-isopropylacrylamide (NIPAM) were polymerized respectively using synthesized macro-RAFT agents. SEM images of PEG-b-PMMA block copolymers have shown that the copolymers have a microporous structure. The critical temperature values of the PEG-b-PNIPAM block copolymers are closer to that of the PNIPAM homopolymer, 32 °C, indicating their usability in drug delivery systems.
