Paragraph 0842, (2021/06/22)
One of the purposes of the present invention is to provide a heterocyclic derivative that has an IAP (particularly XIAP) binding (inhibiting) activity. Another of the purposes of the present invention is to provide a heterocyclic derivative that has an IAP (particularly XIAP) binding (inhibiting) activity and exhibits a protein degradation induction activity. The present invention provides a compound represented by formula (I) (the symbols in the formula are as defined in the present Description) and salts thereof.
Ring size changes in the development of class I HDAC inhibitors

, p. 1387 - 1401 (2021/07/06)
Five pathways involving different ring structures led to generation of fourteen thienylbenzamides (7–20) which display the structure-activity relationships of class I HDAC inhibitors. All the synthesised compounds inhibit HDAC1 and HDAC2 selectively over other isoforms and many inhibit DLD1 and HCT116 cells more effectively than a parent compound. Compounds 8 and 16 inhibit HCT116 cells by activation of the apoptosis pathway.
Ortho-Bromo(propa-1,2-dien-1-yl)arenes: Substrates for domino reactions
Masters, Kye-Simeon,Wallesch, Manuela,Braese, Stefan
, p. 9060 - 9067 (2011/12/03)
o-Bromo(propa-1,2-dien-1-yl)arenes exhibit novel and orthogonal reactivity under Pd catalysis in the presence of secondary amines to form enamines (concerted Pd insertion, intramolecular carbopalladation, and terminative Buchwald-Hartwig coupling) and of amides to form indoles (addition, Buchwald-Hartwig cyclization, and loss of the acetyl group). The substrates for these reactions can be accessed in a reliable and highly selective two-step process from 2-bromoaryl bromides.
3-(o-Trifluoroacetamidoaryl)-1-propargylic esters: common intermediates for the palladium-catalyzed synthesis of 2-aminomethyl-, 2-vinylic, and 2-alkylindoles

scheme or table, p. 8916 - 8929 (2009/12/07)
3-(o-Trifluoroacetamidoaryl)-1-propargylic esters have been used as common synthetic intermediates for the preparation of a variety of 3-unsubstituted 2-substituted indoles. Treating ethyl 3-(o-trifluoroacetamidoaryl)-1-propargylic carbonates unsubstituted or containing an aryl substituent at the propargylic carbon with piperazines and Pd(PPh3)4 in THF at 80 °C affords 2-(piperazin-1-ylmethyl)indoles in excellent yields. Good to excellent yields of 2-aminomethylindoles are also obtained with other secondary amines. Ethyl 3-(o-trifluoroacetamidoaryl)-1-propargylic carbonates bearing an alkyl substituent at the propargylic carbon and ethyl 3-(o-trifluoroacetamidoaryl)-1-propargylic acetates disubstituted at the propargylic carbon give 2-vinylic indoles with the Pd(OAc)2/PPh3 combination and Et3N in THF at 80 °C. Formation of 2-vinylic indoles is quite stereoselective, generating trans vinylic derivatives, at least with the substrates that we have investigated. In the presence of formic acid, Et3N, and Pd(PPh3)4 in MeCN at 80 °C, ethyl 3-(o-trifluoroacetamidoaryl)-1-propargylic carbonates afford 2-alkylindoles in good to excellent yields.
2-Alkylindoles via palladium-catalyzed reductive cyclization of ethyl 3-(o-trifluoroacetamidophenyl)-1-propargyl carbonates

, p. 7721 - 7725 (2008/03/30)
The reaction of ethyl 3-(o-trifluoroacetamidophenyl)-1-propargyl carbonates with formate anions in the presence of Pd(PPh3)4 affords 2-alkylindoles in good to excellent yields.
Intramolecular cyclization reactions of unsaturated amino Fischer chromium carbenes forming indoles and quinolines
S?derberg, Bj?rn C. G.,Shriver, James A.,Cooper, Seth H.,Shrout, Timothy L.,Helton, E. Scott,Austin, Lucinda R.,Odens, Herman H.,Hearn, Brian R.,Jones, Paula C.,Kouadio, Tiara N.,Ngi, Tan H.,Baswell, Rachel,Caprara, H. John,Meritt, Mark D.,Mai, Than T.
, p. 8775 - 8791 (2007/10/03)
A thermally induced intramolecular annulation reaction of N-(2-alkenylphenyl)amino substituted Fischer chromium carbenes has been extensively examined. The carbene complexes were prepared in moderate to good yields by reaction of 2-aminostyrenes with intermediately formed acyloxy substituted carbenes. Upon heating, the thermally labile carbenes decomposed producing indoles and quinolines as the major products. The product distribution was found to be highly dependent on the substitution pattern and electronic properties of the starting material, and on the solvent used.
