Advances in enzymatic transformation of penicillins to 6-aminopenicillanic acid (6-APA).
TL;DR: Improvements in purification, stability, and immobilization of the enzymes, (i.e. penicillin acylases) used for these transformations of penicillins to 6-aminopenicillanic acid (6-APA), are focused on.
Journal ArticleDOI
Applications of Ultrasound in Organic Synthesis - A Green Approach
Journal ArticleDOI
Enzyme‐catalyzed regioselective synthesis of sugar esters and related compounds
John F. Kennedy,Harish Kumar,Parmjit S. Panesar,Satwinder S. Marwaha,Rita Goyal,Anupama Parmar,Sukhwinder Kaur +6 more
TL;DR: A comprehensive and illustrative survey of the regioselective synthesis of esters of sugars and related compounds using lipases is given in this article, where the main emphasis is given to the screening and use of commercially available lipases for the enzymatic esterification of neutral monosaccharides, disaccharide, sugar alcohols and their selected ether and ester derivatives.
Journal ArticleDOI
Recent Trends in Enzymatic Conversion of Cephalosporin C to 7-Aminocephalosporanic Acid (7-ACA)
TL;DR: 7-Aminocephalosporanic acid (7-ACA) is the basic building block used in the synthesis of many important semisynthetic cephalosporin antibiotics that are of current interest in the biopharmaceutical industry.
Journal ArticleDOI
Ultrasound promoted ZrCl4 catalyzed rapid synthesis of substituted 1,2,3,4-tetrahydropyrimidine-2-ones in solvent or dry media
Harish Kumar,Anupama Parmar +1 more
TL;DR: Sonication of aromatic aldehydes, urea and ethyl acetoacetate in presence of solvent or solvent-less dry media with supported-zirconium (IV) chloride as catalyst gives 6-methyl-4-substitutedphenyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid ethyl esters proficiently in high yields.
