  • Microbial hydroxylation of steroids. 8. Incubation of Cn halo- and other substituted steroids with Cn hydroxylating fungi
    作者:Herbert L. Holland、Everton M. Thomas
    DOI:10.1139/v82-027
    日期:1982.1.15

    A series of C-21 substituted progesterone derivatives (R = F, Cl, Br, CH3) has been prepared, and incubated the C-21 hydroxylating fungus A. niger. No biotransformation was observed where R = Cl, Br, or CH3, but a minor amount of hydroxylation occurred at an unidentified site where R = F. Two C-11β substituted progesterone derivatives (R = F, OH) were converted to the corresponding C-11 ketone by the C-11α hydroxylator R. stolonifer, but a C-11β hydroxylator (C. lunata) was unable to perform a similar transformation with a C-11α hydroxy substrate. C. lunata hydroxylated a C-11β fluoro substrate at C-14α and C-21 in low yield. C-7α and -7β-hydroxy androst-4-ene-3,17-diones were prepared and incubated with C-7β hydroxylating (R. stolonifer) and C-7α hydroxylating (M. griseocyanus) fungi respectively. No ketone formation was observed. Similarly, the C-6β hydroxylator R. arrhizus was unable to transform a C-6α-hydroxy substrate or C-6α- or C-6β-hydroxy-B-norsteroids. No oxidation at halogen was observed for any of the substrates used. 13C–19F coupling constants for 11β-fluoroprogesterone suggest the presence of through space interactions between fluorine and both C-18 and C-19.

    一系列C-21取代孕酮生物(R = F、Cl、Br、CH3)已经制备,并与C-21羟化真菌A. niger培养。观察到当R = Cl、Br或 时未发生生物转化,但当R = F时,在未知位置发生了少量羟基化。两种C-11β取代孕酮生物(R = F、OH)被C-11α羟化酶R. stolonifer转化为相应的C-11酮,但C-11β羟化酶(C. lunata)无法使用C-11α羟基底物进行类似转化。C. lunata在低产率下将C-11β底物羟化为C-14α和C-21。制备了C-7α和-7β-羟基雄烯-4-烯-3,17-二酮,并分别与C-7β羟化(R. stolonifer)和C-7α羟化(M. griseocyanus)真菌培养。未观察到酮形成。同样,C-6β羟化酶R. arrhizus无法转化C-6α-羟基底物或C-6α-或C-6β-羟基B-诺甾醇。未观察到任何底物的卤素氧化。11β-氟孕酮13C–19F偶合常数表明与C-18和C-19之间存在空间相互作用。

  • A stereoselective total synthesis of Δ9-progesterone via an intramolecular cycloaddition reaction
    作者:Hideo Nemoto、Mitsuo Nagai、Keiichiro Fukumoto、Tetsuji Kametani
    DOI:10.1016/s0040-4039(00)98766-5
    日期:1985.1
    A stereoselective total synthesis of 19-nor-Δ9(10)-progesterone (14) was achieved through des-A B-aromatic steroid (3) which was obtained by an intramolecular cycloaddition of the -quinodimethane generated from the thermolysis of 3-isopropenyl-5-(4-metho-xybenzocyclobutenyl)pentan-2-one-2-ethylene ketal (2), and the compound (14) thus obtained was further converted into Δ9-progesterone (18).

  • Structure and biological activity of steroids. Part I. The hydrogen-bonding properties of halogenohydrins in the t-butylcyclohexane and steroid series
    作者:Anne B. Devine、Ruth E. Lack

    Following on the discovery of the importance of 17α-acetoxy-9α-fluoro-11β-hydroxyprogesterone in the control of ovulation in sheep, a study has been made of the hydrogen-bonding properties of the 9α-halogeno-11β-hydroxyprogesterones and model compounds in the 5α-cholestane and t-butylcyclohexane series by use of infrared and nuclear magnetic resonance spectroscopy, with a view to discovering if increase
    在发现17α-乙酰氧基-9α--11β-羟基孕酮在控制绵羊排卵中的重要性之后,对9α-卤代11β-羟基孕酮和模型化合物的氢键性质进行了研究。用红外和核磁共振光谱法研究了5α-胆甾烷叔丁基环己烷系列,以发现活性的增加是否与酶电子供体位键的增加有关。红外和核磁共振光谱均表明,β-卤素原子的存在增加了与二恶烷丙酮的氢键结合,而11β-羟基则可能由于对羟基自由旋转的空间位阻而显示出增加的氢键结合。
