摘要:Hydrolase-Catalysed Dynamic Kinetic Resolutions Of Chroman-2-Ol And 3-Methyl Chroman-2-Ol Can Be Effected With Up To 88% Conversion And 92% Ee Through The Use Of Organic Solvents. Extension To The Resolution Of The Tolterodine Precursor 1 Proved More Challenging. The Presence Of The Remote Phenyl Substituent Had A Significant Impact On The Resolution And It Was Not Possible To Achieve High Enantioselectivity Together With Efficient Conversion From The Focussed Panel Of Enzymes Screened.
