摘要:The present invention provides methods for the synthesis of ketones involving a Ni/Zr-mediated coupling reaction. The Ni/Zr-mediated ketolization reactions can be used in the synthesis of halichondrins (e.g., halichondrin A, B, C; homohalichondrin A, B, C; norhalichondrin A, B, C), and analogs thereof. Therefore, the present invention also provides synthetic methods useful for the synthesis of halichondrins, and analogs thereof. Also provided herein are compounds (i.e., intermediates) useful in the synthesis of halichondrins, and analogs thereof. In particular, the present invention provides methods and compounds useful in the synthesis of compound of Formula (H3-A).

标 题 :Stereoselective synthesis of selective estrogen receptor down-regulators
权利人:BAYER SCHERING PHARMA AG; ASTRAZENECA AB
摘要:The present invention relates to stereoselective synthesis of 7-α-substituted estra-4-ene-3,17-diones. Such compounds are valuable intermediates in the synthesis of 7-α-substituted estra-1,3,5(10)-triene-3,17-diols. n Key step in this synthesis is reacting a 3-keto-4,6-estradiene with a Grignard reagent selected from the group consisting of a magnesium-halide alkyl halide having at least 3 carbon atoms, a magnesium-halide alkenyl halide having at least 3 carbon atoms, and a magnesium-halide alkynyl halide having at least 3 carbon atoms, in the presence of a catalyst system comprising CuI. n The obtained 7α-alkyl, alkenyl and alkynyl halides can be used for the synthesis of pharmaceutically actice 7-α-substituted estra-1,3,5(10)-triene-3,17-diols (antiestrogens).
