The boron trifluoride-etherate mediated cyclization of 2-arylthio-ketones 1a-h at ambienttemperature gave 3-aryl-substituted benzothiophenes 2a-h in excellent yield. None of the rearranged 2-aryl-substituted benzothiophenes were observed.

The present disclosure relates to compounds that act as antagonists via binding to the ER ligand binding domain non-covalently or covalently, or act as both antagonists and ER protein degraders, and the synthesis of the same. Further, the present disclosure teaches the utilization of such compounds in a treatment for proliferative diseases, including cancer, particularly breast cancer, and especially ER+ breast cancer.

Targeting LRH‐1: Virtualscreening and molecular modeling were used to identify novel antagonists of liverreceptor homolog‐1 (LRH‐1), an emerging therapeutic target for breast cancer. Hit compounds were synthesized and biologically assayed, and the preliminary results suggest that raloxifene‐based analogues, substituted at the position C‐7 of the benzothiophene ring, might generate an inactive protein

Abstract The preparation of 3-aryl benzofuran and benzothiophenes and their dimers at 2-position and, 2-aryl indoles and their 3-position dimers preparation is described. Graphical Abstract
RhH(PPh3)4 and 1,2-bis(diphenylphosphino)ethane (dppe) catalyzed the organothio exchange reaction of α-organothioketones and organic disulfides. The reaction was affected by the structure of the substrate: α-phenylthio and α-alkylthio aryl ketones reacted effectively with diaryl and dialkyl disulfides; α-phenylthio dialkyl ketones reacted with diaryl disulfides but not with dialkyl disulfides; diaryl disulfides with electron-donating p-substituents were more reactive than those with electron-withdrawing p-substituents.
