The synthesis of several cyclic dialkoxy orthoesters is reported. Acidhydrolysis of these orthoesters under kinetically controlled conditions gives the corresponding hydroxy esters only. Conformationally rigid cyclic mixed orthoesters give a hydroxy ester by exclusive loss of the axial alkoxy group. A cyclic orthoester can have nine different gauche conformations. It is shown that they are hydrolyzed
The present invention relates to a 11β-hydroxysteroid dehydrogenase 1 inhibitor comprising a compound represented by the formula (1):
wherein each symbol is as defined in the description,
or a salt thereof, or a prodrug thereof. The 11β-hydroxysteroid dehydrogenase 1 inhibitor of the present invention has a superior activity, and is useful as a pharmaceutical agent such as agents for the prophylaxis or treatment of diabetes, insulin resistance, obesity, abnormal lipid metabolism, hypertension and the like, and the like.
Compounds represented by the formulas (I) (II) wherein each symbol is as defined in the specification, and a pro-drug thereof have a superior renin inhibitory activity, and are useful as agents for the prophylaxis or treatment of hypertension, various organ damages attributable to hypertension and the like.
