  • Conformation of 2,3-caranediols and 3-hydroxy-2-caranones 
    Arbuzov B.; Isaeva Z.; Povodyreva I.; Ratner V. (1979)
    1. The hydroxyl groups in 2β,3α-caranediol occupy diaxial positions, and those in 2α,3β-caranediol occupy diequatorial positions. 2. 2α,3α-Caranediol and 2β,3β-caranediol exist predominantly in forms with an axial tertiary ...
  • Epoxidation of diastereomeric 4-(α-hydroxyethyl)-3-carenes 
    Isaeva Z.; Ibragimova N.; Povodyreva I.; Timoshina T. (1979)
    Epoxldation of diastereomeric 4-(hydroxyethyl)- and 4-(acetoxyethyl)-3-carenes stereospecifically gives trans isomers of the corresponding epoxides. © 1979 Plenum Publishing Corporation.
  • Hydrolysis of 4-acetyl-3α, 4α-epoxycarane 
    Arbuzov B.; Ibragimova N.; Povodyreva I. (1980)
    The acid hydrolysis of 4-acetyl-3α,4α-epoxycarane proceeds with opening of the oxide ring at the carbon atom not attached to an electronegative substituent to give the diol 4β-acetyl-3β, 4α-caranediol. © 1980 Plenum ...
  • Hydroxymercuration-demercuration of 2-carene 
    Arbuzov B.; Ratner V.; Isaeva Z.; Belyaeva M.; Povodyreva I. (1979)
    trans-3-Caranol, a-terpineol, p-5-methene-1,8-diol, and p-6-menthene-5,8-diol are formed in the hydroxymercuration-demercuration of 2-carene. © 1979 Plenum Publishing Corporation.
  • Oxidation of 3-carene by thallium(III) acetate 
    Ratner V.; Isaeva Z.; Povodyreva I.; Efremov Y.; Arbuzov B. (1983)
    Oxidation of 3-carene by thallium(III) acetate leads to 3-acetyl-6,6-dimethylbicyclo[3.1.0]hexane; 2-(p-tolyl)-2-propanol; 3 /gb,4 /gb-caranediol, 1-(p-menthene)-5,8-diol, and a product with an assumed structure of ...
  • Oxidation of 3-carene with mercuric acetate 
    Isaeva Z.; Arbuzov B.; Ratner V.; Povodyreva I. (1965)
    The oxidation of 3-carene with mercuric acetate was studied. The oxidative acetylation of 3-carene with mercuric acetate leads to a less complex mixture of products than oxidation with lead tetraacetate. The main products ...
  • Oxidation of carene by thallium(III) acetate 
    Ratner V.; Isaeva Z.; Povodyreva I.; Goryachkina N.; Efremov Y.; Arbuzov B. (1983)
    2-p-Tolylpropanol-2, p-menth-1,8-dien-3-ol, p-menth-1-en-3α, 8-diol, p-menth-1-en-3β, 8-diol, p-menth-1-en-3-on-8-ol, p-menth-1,8-dien-5,6-diol, and 2,3-dihydroxy-1,8-cineole are formed during the oxidation of 2-carene by ...
  • Structures of unsaturated acetic esters formed in the reaction of 2-pinene oxide with acetic anhydride 
    Arbuzov B.; Isaeva Z.; Povodyreva I. (1965)
    The bicyclic acetate obtained in the reaction of 2-pinene oxide with acetic anhydride is a mixture of (-)-and (±)-trans-pinocarveol acetates; one of the monocyclic acetates obtained is a mixture of (+) and (±)-trans-carveol ...
