  • Stereocontrolled synthesis of serricornin
    Patent number: 5817882
    Abstract: Serricornin, the attractant pheromone of the cigarette beetle, is synthesized in high enantiomeric and diastereomeric purity via a series of reactions of asymmetric 2-(1-haloalkyl)-1,3,2-dioxaborolanes with Grignard reagents, which lead to the key intermediate ?,S-(R*,R*,R*)!-2-ethyl-3,5-dimethyl-l-octen-6-ol. Oxidative cleavage of the carbon-carbon double bond of ?S-(R*,R*,R*)!-2-ethyl-3,5-dimethyl-l-octen -6-ol with osmium tetroxide and sodium periodate yields serricornin.

  • Haze-free boronated antioxidant
    Patent number: 4927553
    Abstract: An additive composition of boronated phenolic antioxidant and anti-haze diol capable of complexing with boric acid as well as organic material protected by the additive composition. A hydrolytically stable additive composition comprising a boronated phenolic antioxidant and a diol member capable of reacting with boric acid formed as a hydrolysis product to form a stable ring structure soluble in a substrate. The additive composition prevents or cures a haze caused by hydrolysis.
    Type: Grant
    Filed: May 6, 1983
    Date of Patent: May 22, 1990
    Assignee: Ethyl Corporation
    Inventors: William E. Wright, Bryan T. Davis, Donald S. Matteson, Gordon G. Knapp
  • Preparation of .alpha.,.alpha.-dihaloalkyl boronic esters
    Patent number: 4701545
    Abstract: Esters of .alpha.,.alpha.-haloalkyl boronic acids are prepared by the addition of an alkali metal dialkylamide, or some other equivalent sterically hindered base to a mixture of a 1,1-dihaloalkane and a trialkyl borate in an organic solvent at a temperature between about -78.degree. C. and +25.degree. C. In one embodiment, diisopropyl (dichloromethyl)borate is formed by the addition of lithium diisopropylamide to a mixture of dichloromethane and triisopropyl borate in the presence of tetrahydrofuran as the solvent medium at a temperature between about -10.degree. C. and +10.degree. C.
