This is an ABSTRACT ONLY.A chemo-enzymatic method for production of ß-thymidine, an intermediate in the synthesis of antiretrovirals, is described. Guanosine and thymine were converted by means of enzymatic transglycosylation to yield 5-methyluridine (5-MU), which was reproducibly synthesised at a 10-20-L scale in 85% yield at a final product concentration of 80 g·L-1. A downstream processing (DSP) protocol was designed to remove reaction components interfering with the subsequent synthetic step. The crystallised 5-MU produced in the biocatalytic reaction was found to behave similarly to commercially available 5-MU, and the integration of the initial biocatalytic and subsequent three-step chemical process to ß-thymidine was successfully demonstrated at bench scale.enß-ThymidineBiocatalysisAntiretroviralsChemo-enzymaticAn integrated chemo-enzymatic route for preparation of ß-thymidine, a key intermediate in the preparation of antiretroviralsArticleGordon, G., Bode, M., Visser, D.
