23,4,5- 13 C 5 ) 5-(diethylphosphono)-2-pentanone ethylene ketal 9. The reaction of this labelled compound with 7-[[(1,1-dimethylethyl)-dimethylsilyl]oxy]-1,6,6a,7,8, 9, 9a, 9b-octahydro-6a-methyl-[6aS-(6aa,7a,9a8,9ba)] cydopenta[f][1]benzopyran-3 (2H)-one 13 gave the benzindenone 14 which was converted to (1,2,3,4,10,19- 13 C 6 )testosterone 17 then, into (1,2,3,4,10- 13 C 5 )19-nortestosterone 18 by
乙酰乙酸乙酯- 13 C 4 和溴乙酸乙酯- 13 C 2 的缩合分七步得到(1,23,4,5- 13 C 5 ) 5-(二乙基膦酰基)-2-戊酮亚乙基缩酮9。反应该标记化合物与 7-[[(1,1-二甲基乙基)-二甲基甲硅烷基]氧基]-1,6,6a,7,8, 9, 9a, 9b-八氢-6a-甲基-[6aS-(6aa, 7a,9a8,9ba)] cydopenta[f][1]benzopyran-3 (2H)-one 13 得到苯并苯酮 14,它被转化为 (1,2,3,4,10,19-13 C 6 )睾酮 17然后,通过还原烷基化方法转化为(1,2,3,4,10- 13 C 5 )19-去甲睾酮18。
