Shaping of a Reactive Manganese Catalyst Enables Access to Polyfunctionalized Cyclohexanes via Enantioselective C(sp3)─H Bond Oxidation of 1,3‐meso Diethers

Angewandte Chemie, EarlyView.
Structural shaping of a highly reactive chiral Mn‐oxo species translates into exceptionally enantioselective C─H oxidation catalyst of cyclohexyl 1,3‐meso diethers (up to >99% ee) leading to polyfunctionalized cyclohexanes. Abstract Chiral polyoxygenated cyclohexanes are valuable constituents of biologically relevant products.

Effect of spironolactone and potassium canrenoate on cytosolic and nuclear androgen and estrogen receptors of rat liver [PDF]

, 1987
Spironolactone and potassium canrenoate are diuretics that are used widely for management of cirrhotic ascites. The administration of spironolactone frequently leads to feminization, which has been noted less frequently with the use of potassium ...

Melt block copolymerization of ε-caprolactone and L-lactide [PDF]

, 1997
AB block copolymers of ε-caprolactone and (L)-lactide could be prepared by ring-opening polymerization in the melt at 110°C using stannous octoate as a catalyst and ethanol as an initiator provided ε-caprolactone was polymerized first.
