摘要

A series of 21-desoxy-21-chlorocorticosteroids that contain a functionalized ester group at 17a has been prepared and examined to separate their systemic activity from topical antiinflammatory activity. Introduction of the functionalized ester group at 17a was carried out by an acid-catalyzed formation of cyclic ortho esters with 17a, 21-hydroxyl groups of corticosteroids and subsequent acid-catalyzed hydrolysis. As for the functional group, ...
