Abstract: Provided are compounds of the formula (and pharmaceutically acceptable salts thereof): wherein: R is hydrogen, methyl, hydroxymethyl or ?-hydroxyethyl; R1 and R2 are independently selected from hydrogen, C1-C6 alkyl, C1-C6 hydroxyalkyl, C3-C8 cycloalkyl, C1-C6 alkenyl, C1-C6 alkynyl, amino, monoalkylamino, dialkylaminoalkyl, and pyrrolidin-1-ylalkyl; and Y is selected from the group consisting of C1-C6 alkyl, substituted and unsubstituted aryl; with the provisos that: (a) if Y is aryl, then at least one of R1 and R2 is other than hydrogen, and (b) if R2 is hydrogen R1 is other than methyl. Also provided are pharmaceutical compositions containing the compounds, and methods for the preparation of the compounds. The compounds are useful, among other things, as prodrugs which can be converted under acidic conditions to thiazolium agents. The compounds can be administered to mammals, including humans, for treatment of various indications.

Abstract: A novel process for the preparation of tricyclo[6.2.2.0.sup.3,8 ]dodecane derivatives is presented. This novel process is applied to the synthesis of the odorant 4-acetyl-1,7,7-trimethyltricyclo[6.2.2.0.sup.3,8 ]-3-dodecene, also known as 4-aceto-6,8a-ethano-1,1,6-trimethyl-1,2,3,5,6,7,8,8a-octahydronaphthalene.
