integration of umpolung and carbon isotope exchange for accessing isotopically labeled α-keto acids through photoredox catalysis is elucidated. This process involves the carbonyl umpolung of C(sp2)-α-keto acids to yield C(sp3)-α-thioketal acids, followed by the carbon isotope exchange of C(sp3)-α-thioketal acids, and ultimately, deprotection to generate carbon-labeled α-keto acids.
阐明了umpolung和碳同位素交换的整合,用于通过光氧化还原催化获得同位素标记的α-酮酸。该过程涉及 C(sp 2 )-α-酮酸的羰基旋转生成 C(sp 3 )-α-硫缩酮酸,然后进行 C(sp 3 )-α-硫缩酮酸的碳同位素交换,最终生成 C(sp 3 )-α-硫缩酮酸。 ,脱保护生成碳标记的α-酮酸。
