  Absolute rates of bromination were measured for two series of derivatives of steroidal ketones 3, enol acetates 1 and enol methyl ether 2. Axial substituents exhibited a large effect on rates, which increased by 15,000 fold on going from (X=CH3; Y=CN) to (X=Y=H). From the bromide ion effect it was concluded that the first step (formation of an intermediate bromonium ion) was reversible and that the

  测量了甾族酮3的两个系列衍生物，烯醇乙酸酯1和烯醇甲基醚2的溴化绝对速率。轴向取代基对速率表现出很大的影响，从（X = CH 3； Y = CN）变为（X = Y = H）时，轴向取代基增加了15,000倍。从溴离子效应可以得出结论，第一步（中间体溴离子的形成）是可逆的，并且第二步（卤代酮4或5或卤代缩醛8或9的形成）与第一步相比较慢。推断该中间体是高度不对称的溴离子，而不是纯的氧碳鎓离子。

  Steroidal derivatives having a bicyclo [3. 2. 1] octane bridged ring of the phyllocladene type on the A ring such as compounds (IVa), (IVb), (XXIV) and (VIIIa) were synthesized starting from 5α-cyanocholestan-3-one by three routes. The route consisting of conversion of the cyano group into an acetyl group, and subsequent cyclization was found to be most preferable for the synthesis.

• Syntheses of Substituted Succinimides by Radical .beta.-Fragmentation of Bicyclic Carbinol Amides. A New Expeditious Synthesis of 2-[2-(Methoxycarbonyl)ethyl]-3-[(methoxycarbonyl)methyl]- 3-methylsuccinimide, the Ring-B Imide of Vitamin B12

  A mild and efficient synthesis of substituted succinimides by radical beta-fragmentation of carbinol amides is described. The carbinol amides studied were generated by treatment of the corresponding alpha,beta-unsaturated ketones with hydrogen cyanide and subsequent hydrolysis of the cyanide intermediates. Photolysis with visible light in the presence of (diacetoxyiodo)benzene (DIB) and iodine of azabicyclic carbinol amides of the types 1-hydroxy-2-azabicyclo[3.3.0] octan-3-one (e.g., 4, 6, and 7) and 1-hydroxy-2-azabicyclo[3.2.1]octan-3-one (e.g., 16, 17, and 21) led to the substituted succinimides in good yields. A novel and operationally simple synthesis of the ring-B imide 28 is described, employing this P-fragmentation reaction on the carbinol amide 7 as the key step. The transformation of the resulting succinimide 11 into the target 28 was accomplished in one step by oxidation of the primary iodide and the phenyl group with RUO(4).
