深圳大學蘇陳良團隊報導了室溫鈀催化碳氧鍵氘解製備氘化藥物。 相關研究成果於2020年12月17日發表於在《德國應用化學》。
在藥物分子中加入氘來研究和改善其生物學特性是藥物發現和開發的關鍵。
該文中,研究人員描述了用於實際合成含苄基位(sp3 C-H)D-摻入的氘化藥物和化學品鈀催化的乙醇和酮中碳氧鍵的室溫氘解反應。該脫氧氘化反應的特點是條件溫和、使用範圍廣、實用性強、化學選擇性高。為了能夠直接使用D 2 O,電催化D 2 O分解適用於按需原位提供D 2。
利用該系統,氘在布洛芬代謝位置(苄基位)的精確結合被證明是一種可持續和實用的方法。

Abstract: Site‐specific incorporation of deuterium into drug molecules to study and improve their biological properties is crucial for drug discovery and development. Herein, we describe a palladium‐catalyzed room‐temperature deuterogenolysis of carbon‐oxygen bonds in alcohols and ketones with D 2 balloon for practical synthesis of deuterated pharmaceuticals and chemicals with benzyl‐site (sp 3 C‐H) D‐incorporation. The highlights of this deoxygenative deuteration strategy are mild conditions, broad scope, practicability and high chemoselectivity. To enable the direct use of D 2 O, electrocatalytic D 2 O‐splitting is adapted to in‐situ supply D 2 on demand. With this system, the precise incorporation of deuterium in the metabolic position (benzyl‐site) of ibuprofen is demonstrated in a sustainable and practical way with D 2 O.
