Abstract
An efficient and reliable method for the preparation of bitritiated‐methylthioribose from a suitably protected 5‐ketoazido‐ribose derivative has been developed. This compound is an essential component in the assay of the microbial enzyme methylthioribose kinase, which is involved in the methionine salvage pathway from methylthioadenosine.
