    Modification of estradiol at the 17-position. Effect of changing the OH group for a transition-metal carbonyl cluster on the estradiol receptor recognition
    摘要:
    The reaction of [Co2(CO)6(17alpha-ethynyl-17beta-estradiol)] (2a) with Fe(CO) 5 in acetone produces [FeCo(CO)6(17alpha-ethynyl-17beta-dehydroxyestradiol)] (3a) as the result of the dehydroxylation ability of the iron pentacarbonyl. The molecular structure of 3a has been investigated not only by NMR spectroscopy but also by use of molecular modeling techniques. The structural data for the organometallic part of the molecule are derived from a single-crystal X-ray determination of the model complex [FeCo(CO)5(PPh3)(H3CC2CH2)], carried out at 123 K: triclinic, P1 (No. 2), a = 10.315(1) angstrom, b = 10.579(1) angstrom, c = 12.989(2) angstrom, alpha = 67.62(1)-degrees beta = 89.44(2)-degrees, lambda = 79.30(2)-degrees, V = 1287.1(7) angstrom3, Z = 2, R(F) = 0.063. The mixed-metal cluster [FeCo(CO)6(HC=C=CH2)] was used as a model of the cation [Co2(CO)6(HC=CCH2)]+, and its structure was rationalized by means of extended Huckel molecular orbital calculations. The biological results obtained from the incubation in vitro of the steroid-organometallic complex 3a with lamb uterine cytosol (used as a source of estradiol receptor) indicate that the absence of the 17-OH group on estradiol prevents the formation of an irreversible (covalent) bond between the metal-labeled steroid and its specific receptor. The biochemical implications of such a change in reactivity are discussed.

    摘要:
    Co2(CO)8与不对称取代的炔烃的反应生成配合物Co2(CO)6(RC2R')(1)。这些催化炔烃到取代苯的环三聚。在这里,我们报道了一些新的配合物的合成和表征1,以及它们在相对温和的条件下与过量炔烃的反应性。报道并评论了新的中间体Co2(CO)4(RC2R')3天桥衍生物(配合物2)的表征以及一些对称和不对称取代的苯的合成。在某些情况下,获得的是炔烃低聚物而不是环三聚体。反应在很大程度上取决于催化剂的类型,所采用的条件以及炔烃上取代基的空间和电子效应,

    Abstract The reactions of Co2(CO)8 with asymmetrically substituted alkynes lead to derivatives Co2(CO)6(RC2R′) (1). Substitution reactions of complexes 1 with PPh3, Ph2P · CH2CH2 · AsPh2 (arphos) and Ph2P · CH2 · PPh2 (dppm) have been attempted. With PPh3 monosubstituted chiral tetrahedral molecules, characterized by two differently substituted acetylenic carbon atoms and by two cobalt atoms with different
