An efficient and cost-effective preparation of di-O-acetyl-D-rhamnal

摘要

We have developed a synthetic route to the frequently utilized deoxysugar building block di-O-acetyl-D-rhamnal originating from the inexpensive starting material methyl α-o-glucopyranoside. Our approach proceeds in five steps with minimal column chromatography purification needed to afford the title compound in good overall yield.
