title: Effect of the alpha-methyl substituent on chemoselectivity in esterase-catalyzed hydrolysis of S-acetyl sulfanylalkanoates. creator: Kumar, Ish creator: Jolly, R S subject: QD Chemistry description: The isomeric compounds 1 and 3, which differ only in the position of a methyl substituent, give opposite chemoselectivities in an esterase-catalyzed hydrolysis reaction. The esterase was chemoselective for the oxoester in 1, but for the thiol ester group in 3. A high enantioselectivity was observed for both 1 and 3. publisher: ACS Publications date: 1999-07-29 type: Article type: PeerReviewed format: application/pdf identifier: http://crdd.osdd.net/open/313/1/jolly1999.pdf relation: http://pubs.acs.org/doi/pdfplus/10.1021/ol990544%2B identifier: Kumar, Ish and Jolly, R S (1999) Effect of the alpha-methyl substituent on chemoselectivity in esterase-catalyzed hydrolysis of S-acetyl sulfanylalkanoates.
