Abstract

Seven new masked analogues of phosphopantothenate, suitable for an evaluation of their potential ability to restore intracellular coenzyme A (CoA) levels, were successfully synthesized in good to moderate yields. The preparation of derivatives masked with (acyl­oxy)alkyl groups was studied particularly in terms of synthetic efficiency, and the possibility of applying different chlorophosphate reagents for the preparation of a variety of masked derivatives was also investigated. Using this methodology, we have successfully synthesized a new chlorophosphate reagent, suitable for the introduction of the (isobutyryloxy)methyl functionality into the prodrug. Additionally, special attention was given to finding mild and economical reaction conditions for phosphorylation of biological molecules.
