BISPHENOL DERIVATIVES AND THEIR USE AS ANDROGEN RECEPTOR ACTIVITY MODULATORS

This invention provides bisphenol derivatives having a structure of formula I. Said compounds are modulators of the androgen receptor activity and are useful in the treatment of various diseases, including prostate cancer, breast cancer, ovarian cancer, endometrial cancer, acne, ovarian cysts, polycystic ovarian disease, age-related macular degeneration, precocious puberty, hirsutism and air loss.

Process for producing bis-alkoxylated diols of bisphenol a from spent polycarbonate discs(PC) or PC waste

This invention provides one-pot reaction for digesting polycarbonate waste with alkylene glycol in the presence of a basic catalyst at 180° C. under normal atmospheric pressure. The digested product mixture was found to consist of bisphenol A (BPA) and monoalkoxylated and bisalkoxylated diols of BPA. Alkoxylation of BPA and monoalkoxylated diols of BPA is performed by adding urea or urea derivative (or carbonic acid ester or amine ester) to the digested product mixture at a high temperature under normal atmospheric pressure to obtain the final product, i.e., bisalkoxylated diols of BPA in high yield. The bisalkoxylated diols of BPA may be used as raw materials to synthesize polymer such as polyurethane (PU) or polyester.

Aromatic ethers and process for producing aromatic ethers

According to a production process, aromatic ethers are producible by reacting phenols with an oxirane compound with use of an anion exchange resin as a catalyst. According to another production process, aromatic ethers having an alcoholic hydroxyl group are producible by a crystallization-purification step of using a solvent having a solubility parameter ranging from 7.5 to 12.5 for purification by crystallization. Further, according to still another production process, producible are aromatic ethers having an alcoholic hydroxyl group, wherein the content of a metal in the aromatic ethers is less than 100 ppm by mass, and the content of a halogen element in the aromatic ethers is less than 100 ppm by mass.
