标题:On The Regioselectivity Of The Protease Subtilisin Towards The Acylation Of Enantiomeric Pairs Of Benzyl And Naphthyl Glycopyranosides. Part 2
摘要:Subtilisin-Catalyzed Esterification Of Several Enantiomeric Benzyl And Naphthyl Glycopyranosides Has Been Investigated. The D-Sugar Derivatives Were All Good Substrates And Subtilisin Regioselectivity Was Similar With All The Compounds Tested,The 3-Oh Being Acylated Predominantly. On The Other Hand,Most Of The L-Glycopyranosides Were Transformed During Longer Reaction Times With A Lower Regioselectivity,The 2-Oh Being Preferentially But Not Exclusively Acylated.
