A Practical Sulfenylation of 2,5‐Diketopiperazines

Sulfurs in action: A practical and simple method has been developed for the introduction of sulfur atoms into 2,5-diketopiperazines (I) under mild conditions. The reaction provides more or less complex epidithiodiketopiperazines (II) and bis-methylthiodiketopiperazines (III).
