  An Efficient Fischer Indole Synthesis of Avitriptan, a Potent 5-HT_1D Receptor Agonist

  摘要：

  An efficient synthesis of the antimigraine drug candidate avitriptan (1, BMS 180048) is reported. The key step is a two-phase Fischer indolization reaction between hydrazine 6 and 5-chlorovaleraldehyde, 20, to give the chloropropylindole 35, which is susceptible to acid-catalyzed degradation under the reaction conditions required for its formation. Sequential coupling of 35 with piperazine, 26, and 4-chloro-5-methoxypyrimidine, 24, gives the title compound in 40-45% overall yield. Significant improvements in the syntheses of the known starting materials, hydrazine 6, 5-chlorovaleraldehyde, 20, and 4-chloro-5-methoxypyrimidine, 24, were also achieved.

  The present invention provides pharmacological compounds including an effector moiety conjugated to a binding moiety that directs the effector moiety to a biological target of interest. Likewise, the present invention provides compositions, kits, and methods (e.g., therapeutic, diagnostic, and imaging) including the compounds. The compounds can be described as a protein interacting binding moiety-drug conjugate (SDC-TRAP) compounds, which include a protein interacting binding moiety and an effector moiety. For example, in certain embodiments directed to treating cancer, the SDC-TRAP can include an Hsp90 inhibitor conjugated to a cytotoxic agent as the effector moiety.

  日期：——

  A variety of different N-(2,2,3-trichloropropyli­dene)amines, N-(2,2,3-trichlorobutylidene)amines, and N-(2,2,5-trichloropentylidene)amines were synthesized for the first time, and their reactivity with regard to hydride reagents was investigated. In this way, N-(2,2,5-trichloropentylidene)amines were evaluated as substrates for the synthesis of piperidines, and N-(2,2,3-trichloropropylidene)amines and N-(2,2,3-trichlorobutylidene)amines were reduced efficiently into the corresponding novel β,β,γ-trichloro-amines by means of sodium cyanoborohydride in methanol in the presence of acetic acid. Furthermore, N-(2,2,3-trichloropropyli­dene)amines were transformed into 2-(chloromethyl)aziridines by lithium aluminium hydride in Et2O, and N-(2,2,5-trichloropentylidene)acetamide was used for the first time as a suitable substrate for the addition of oxygen, nitrogen, and sulfur nucleophiles in good yields.

  Enabled by nickel catalysis, a mild and general catalytic method for C-alkylation of nitroalkanes with unactivated alkyl iodides is described. Compatible with primary, secondary, and tertiary alkyl iodides; and tolerant of a wide range of functional groups, this method allows rapid access to diverse nitroalkanes.

  Cobalt (II) chloride in acetonitrile catalyses the cleavage of a wide variety of ethers with acyl halides under mild conditions to give the corresponding esters in good yields. Acyclic aliphatic ethers are cleaved to the corresponding ester and chlorides whereas the cyclic aliphatic ethers give rise to the ω-chloroesters. The benzyl ethers can be converted to the corresponding esters along with the
