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).

发明人：MURTHI KRISHNA K; SMITH CHASE C
权利人:GPC BIOTECH INC
摘要:The present invention relates to novel compositions of methotrexate-containing heterodimeric probe molecules, also known as chemical inducers of dimerization (CID), useful in three-hybrid assays. The invention further relates to synthesis of said compositions and their intermediates. Another aspect of the invention is a method for using the heterodimeric probe molecules described herein in drug screens to identify potential protein targets to a given ligand, optimize protein-ligand interactions, or identify potential ligands for a given protein target. In certain embodiments, the invention contemplates the synthesis of the following methotrexate-containing heterodimeric probe:

摘要:PCT No. PCT/FR97/00803 Sec. 371 Date Jan. 19, 1999 Sec. 102(e) Date Jan. 19, 1999 PCT Filed May 6, 1997 PCT Pub. No. WO97/43231 PCT Pub. Date Nov. 20, 1997The invention features a useful method for the synthesis of fluorinated derivatives. It is characterized in that it comprises at least one step in which a substrate comprising one sp3 hybridizing halogenophore carbon bearing at least two halogens, at least one of which is a halogen of an atomic number higher than that of fluorine, which halogenophore carbon is coupled to at least one weak hybridization atom bearing an unsaturation, is subjected to the action of one reagent comprising at least one defined compound selected among those constituted by the association of one Bronstedt base with a defined number n of hydrofluoric acid, n being at least 3 and at most 20, advantageously 15, preferably 10. This invention is useful in organic synthesis.

摘要:There is described a process for the synthesis of a fluoronucleoside compound, said process comprising mixing a substrate and an enzyme from Streptomyces cattelya as catalyst. The process may be used to produce an 18 F labelled fluoronucleoside compound. There is also described an enzyme derived from Streptomyces cattelya which has the capacity to catalyse the synthesis of a fluoronucleoside compound.
