The cannabinoid receptor antagonist SR144528 was synthesized by an approach that enabled the incorporation of high specific activity tritium label while circumventing the lability of the target compound to catalytic hydrogenation. Lithium aluminum tritide of less than maximum specific activity was employed to introduce tritium, resulting in an H/T incorporation indicative of no kinetic isotope effect for the hydride/tritide reduction of a methyl benzoate.

大麻素受体拮抗剂SR144528的合成采用了一种方法,该方法能够在避免目标化合物对催化加氢的敏感性的情况下,准确纳入高比活性的氚标签。使用的锂铝氚化物的比活性低于最大比活性,以引入氚,导致氢/氚的引入表明在甲基苯甲酸酯的氢化/氚化还原过程中没有动力学同位素效应。版权 © 2005 John Wiley & Sons, Ltd.
