Air-stable μ2-hydroxyl bridged cationic binuclear complexes of zirconocene perfluorooctanesulfonates: their structures, characterization and application
binuclear structures: (i) [CpZr(OH2)3]2(μ2-OH)2(OSO2C8F17)4·2THF·4H2O (1a·2THF·4H2O), (ii) [n-BuCpZr(OH2)3]2(μ2-OH)2(OSO2C8F17)4·6H2O (2a·6H2O), and (iii) [t-BuCpZr(OH2)3]2(μ2-OH)2(OSO2C8F17)4·2C3H6O·8H2O (3a·2C3H6O·8H2O). The ligands of water and organic molecules in the complexes originated from the moist air and solvent during their recrystallization. These complexes were characterized with different

Non-steroidal androgen receptor modulating compounds of the general formula (I), their pharmaceutically acceptable salts, preparation process and pharmaceutically compositions containing the said compounds are disclosed. Such compounds of the general formula (I) or their pharmaceutically acceptable salts can be used for preparing non-steroidal medicines to treat and/or prevent conditions or diseases such as prostatic hyperplasia, prostate cancer, hirsutism, severe hormone-dependent alopecia or acne, etc. as a result of androgen receptor antagonistic activities.
HCl-catalyzed Mannich reaction of cyclic ketone, aromatic aldehyde, and aromatic amine proceeded smoothly in water in the presence of SDS to afford the corresponding β-amino ketone with high anti selectivity.
