Imines and derivatives. Part 21. A study of structural and mechanistic aspects of the synthesis of imine, imine oxide, and oxime derivatives of 2,2,4,4-tetramethylcyclobutane-1,3-dione by X-ray crystallography and nuclear magnetic resonance and ultraviolet spectroscopy

The dinitrone derivatives (5a, b) of 2,2,4,4-tetramethylcyclobutane-1,3-dione were synthesised by peroxyacid oxidation of the corresponding di-imines (3a, b). X-Ray crystallographic analysis of di-imine (3a) and the hydroxyimino nitrone isomers (6a, b) indicate a marked buttressing effect leading to an exclusive preference for the trans geometry in di-imine (3a) and dinitrone (5a).

The present invention relates to a class of bifunctional chimeric heterocyclic compounds for targeted degradation of androgen receptors and use thereof, and specifically provides a compound of formula (I), or an isotopic compound thereof, or an optical isomer thereof, or a tautomer thereof, or a pharmacologically acceptable salt thereof, or a prodrug thereof, or a solvate thereof, wherein ARB is an androgen receptor recognition/binding part, L is a link part, and U is a ubiquitin protease recognition/binding part; and the three parts are connected by means of chemical bonds. The compound can perform the targeted degradation on androgen receptors in prostate cancer cells, and suppress the proliferation of the prostate cancer cells, and also show good metabolic stability and pharmacokinetic properties. The compound has good application prospect in the preparation of targeted chimeras for protein degradation of androgen receptors and in the preparation of drugs for treating the related diseases regulated by the androgen receptors.
