    摘要: Organocatalysts, particularly proline sulfonamide organocatalysts, having a first general formula as follows are disclosed. Embodiments of a method for using these organocatalysts also are disclosed. The method comprises providing a disclosed organocatalyst, and performing a reaction, often an enantioselective or diastereoselective reaction, using the organocatalyst. Solely by way of example, disclosed catalysts can be used to perform aldol reactions, conjugate additions, Michael additions, Robinson annulations, Mannich reactions, α-aminooxylations, α-hydroxyaminations, α-aminations and alkylation reactions. Certain of such reactions are intramolecular cyclizations used to form cyclic compounds, such as 5-or 6-membered rings, having one or more chiral centers Disclosed organocatalysts generally are much more soluble in typical solvents used for organic synthesis than are known compounds. Moreover, the reaction yield is generally quite good with disclosed compounds, as is their enantioselective and diastereoselective effectiveness.

    摘要: 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

    摘要: A method for making epothilones and epothilone analogs is described, as are novel compounds made by the method. Exemplary novel compounds include those according to the formula: With respect the formula, G is selected from the group consisting of R2 substituents independently are selected from the group consisting of H and lower alkyl groups; Z is selected from the group consisting of the halogens and —CN; M is selected from the group consisting of O and NR3; R3 is selected from the group consisting of H, lower alkyl, R4CO, R4OCO, and R4SO2; R4 is selected from the group consisting of H, lower alkyl, and aryl; T is selected from the group consisting of CH2, CO, HCOH and protected derivatives thereof; W is H or OR; and X and Y independently are selected from the group consisting of O, NH, S, CO, and C. Embodiments of the method provide convenient access to analogs of the epothilones, such as those having alternate stereochemistry and those containing an ester, amide, thioester, or alkyne moieties in the macrocycle.
