                                    A series of new 2-substituted 2-methyl-4H-1,3-benzodioxin-4-ones 1 have been synthesized and fully characterized.  This study involves fifteen compounds of which fourteen are orthoesters, containing tertiary aliphatic alkoxy groups.  One compound contains a tert-butylperoxy group and one a 3-beta-cholesteryloxy group in the 2-position.  The hydrolysis of these compounds 1 was followed in enzymatic and non-enzymatic media to clarify whether they are true prodrugs of aspirin.  Two compounds 1 were additionally tested in vivo as potential topical keratolytics.
