  • Patent number: 6972338
    Abstract: The invention relates to a series of novel alkoxylated mono alkyl glyceryl ester phosphobetaine compounds, which are exceptional surface active agents that provide outstanding foam and are very mild to the hair and skin, in addition because of the presence of the ester linkage these materials are not persistent in the aquatic environment. This lack of persistence in the aquatic environment makes these materials greener and environmentally friendly than other non-ester containing compounds. The compounds, because they contain a pendant ionizable phosphate group and a quaternary amine compound are amphoteric surfactants that is they contain both a positive and negative charge in the same molecule. This combination of properties makes these polymers ideally suited for use in personal care applications.

  • Patent number: 6958401
    Abstract: A method for making epothilones and epothilone analogs is described, as are novel compounds made by the method. One embodiment of the method was used to synthesize epothilone B by a convergent approach that entailed Wittig coupling of an ylide derived from phosphonium bromide with an aldehyde. The former was prepared from propargyl alcohol by a nine-step pathway which installed both trisubstituted double bonds with clean Z configuration. Macrolactonization of a resulting seco acid provided the following intermediate diene epothilone analog. Selective saturation of the 9,10-olefin and subsequent epoxidation provided epothilone B.
