  • Dihalocarbene reactions with steroid olefins

    Creator:
    Cornelia, Richard Hartman
    Abstract:
    Dihalocarbenes have been generated mainly by thermal decomposition of sodium trihaloacetate and phenyl (trihalomethyl)mercury, and give gem-dihalocyclopropyl adducts with various steroid olefins. A new procedure involving the use of sealed tubes makes possible the addition of dihalocarbenes to sterically hindered olefins. In this manner, 7-cholestenyl benzoate when treated with PhHgCC1₃...

  • Oxymercuration of cyclodeca-1,2,5,8-tetraene

    Creator:
    Hong, Pak-Kong
    Abstract:
    The reactions of cyclodeca-1, 2, 5, 8-tetraene with mercuric salts in solvents of varying nucleophilicity are described. Instead of forming the usual oxymercuration products reported for reactions of olefins and allenes with mercuric salts, the major products obtained in the present cases result from the initial electrophilic addition of the...

  • Thermal [pi]-route rearrangement of 4-cycloheptane-1-methyl acetate

    Creator:
    Schick, Lawrence Edward
    Abstract:
    Pyrolysis of 4-cycloheptene-l-methyl acetate under flow conditions at 285° gives only rearranged bicyclic acetates and hydrocarbons rather than the anticipated simple elimination product methylenecyclohept- 4-ene. These rearranged acetates have the same structures and are formed in virtually the same relative percentages as those observed in the "π- route" solvolysis of...

  • The synthesis and chemistry of strained bicyclic systems

    Creator:
    Scerbo, Louis
    Abstract:
    A facile route to bicyclo(2.1.1)hexanes was developed involving the intramolecular photocyclization of 1, 5-hexadien-3-one to bicyclo(2.1.1)hexan-2-one. A study of the chemistry of bicyclo-(2.1.1)hexan-2-one was undertaken. Deuterium exchange and borohydride reduction demonstrated the strain present in the ketone. Further evidence was obtained from the failure to introduce substituents alpha to the...

  • Steroid-dihalocarbene reactions

    Creator:
    Damewood, John Roderick
    Abstract:
    Dihalocarbenes have been generated by thermal decomposition of sodium trichloroacetate and tribromomethylphenylmercury, and give mono dihalocyclopropyl adducts with steroid dienes. Such compounds offer an easy starting point for the synthesis of unusual derivatives of potential biological interest. Under the same conditions, however, addition to non-conjugated double bonds does not take...

  • Conformation and reactivity studies of some bicyclo(3.3.1) nonane derivatives

    Creator:
    Sturmer, David Michael
    Abstract:
    New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared from phenol and acrylonitrile via a novel intramolecular S[subscript N]2 cyclization process. A Friedel-Crafts cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated ketone from 4-cyclohexene carboxaldehyde. The formation of the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...

  • Formation of alkyl-and dialkylcarbenes. The 3-cyclohexenyl carbinyl carbene system

    Creator:
    Crouse, Dale McClish
    Abstract:
    The 3-cyclohexenyl carbinyl carbene species was formed by the thermal decomposition of the p-toluenesulfonylhydrazone sodium salt and by oxidation of the hydrazone. Several oxidizing agents were studied. The products were investigated under aprotic and protic conditions and at various temperatures. The diazocompound was formed as an intermediate and found to...
