  • Patent number: 5037992
    Abstract: The present invention is directed to a process for sulfating unsaturated alcohols using inexpensive reagents and mild reaction conditions. The process comprises reacting an unsaturated alcohol of the formula R--OH, wherein R is a C.sub.8 -C.sub.22 alkenyl group, with an ether sulfate of the formula R.sup.1 (OCH.sub.2 CH.sub.2).sub.n OSO.sub.3 M, wherein R.sup.1 is a C.sub.1 -C.sub.18 hydrocarbyl group, n is an integer from 1 to 10, and M is an alkali metal, to form an unsaturated sulfate; said reaction being carried out in the presence of a catlaytically effective amount of an acid catalyst. The mole ratio of unsaturated alcohol reactant to ether sulfate ranges from about 0.5:1 to about 2:1. In this process the sulfation occurs primarily at the hydroxyl group of the unsaturated alcohol, with minimal sulfation at the olefinic moiety of said alcohol.

  • Patent number: 4847303
    Abstract: The present invention involves compounds having the structure: ##STR1## wherein: (a) --A.sup.1 is selected from the group consisting of --OH, --H, and --O.sub.2 CR;(b) --A.sup.2 is selected from the group consisting of unsubstituted or substituted, saturated or unsaturated, straight, branched and cyclic alkyl having from 1 to about 10 carbon atoms;(c)--A.sup.3 is selected from --C(CH.sub.3).sub.3, --Si(CH.sub.3).sub.3, and --CF.sub.3 ; and(d) --Y is selected from certain low molecular weight alkyl chains which terminate in specific unsaturated functional groups: ##STR2## and aldehydes in the form of their acetals; pharmaceutical compositions comprising such compounds; and methods for treating inflammation by administering such compounds.

  • Patent number: 4708966
    Abstract: The present invention relates to novel specifically-substituted phenyl compounds, especially substituted di-tert-butyl phenol derivatives, which are effective as anti-inflammatory, analgesic and/or antipyretic agents. These phenyl compounds are substituted with a low molecular weight alkyl chain which terminates in a specific unsaturated functional group. These unsaturated functionalities are --C.tbd.CH, C.dbd.CH.sub.2, C.dbd.C.dbd.CH.sub.2, and aldehydes in the form of their acetals.The present invention further relates to pharmaceutical compositions which contain an anti-inflammatory agent of the present invention and a pharmaceutically-acceptable carrier.Finally, the present invention relates to methods for treating diseases characterized by inflammation, such as rheumatoid arthritis and osteoarthritis, in humans or lower animals.
