Front Cover: Synthetic Approaches to Ribosyl Adenosine 5′,5′′‐Diphosphate Fragment of Poly(ADP‐ribose)

The Front Cover illustrates synthetic approaches to the ribosyl adenosine 5,5‐diphosphate fragment of poly(ADP‐ribose). In the cover image, Sugoroku, known as a traditional Japanese board game, represents which routes are more efficient and straightforward to reach the goal. Cover designed by N. Kosaka.
