The 19 esters in Table I were prepared from (+)-2 alpha-tropanol, (-)-2 beta-tropanol, (+/-)-3-quinuclidinol, and a variety of non-glycolic acids in order to compare their central and peripheral activities with those of the glycolates reported in the previous paper. The results (Table II) showed that esters 6 and 17 were approximately equivalent to one another and to atropine, that 8 was equal in both central and peripheral activity to reference glycolates, that 9 and 19 were less active than 8 but 9 had a substantially reduced central activity, and that 10 and 11 were more active than the methoxy analogue reported earlier.

3 alpha-Phenyl-3 beta-tropanyl phenyl ketoxime furnished 3 alpha-phenyltropane-3 beta-carboxylic acid which on esterification gave the ethyl ester XV, the tropane analog of meperidine (1). The ketobemidone analog XXI was prepared from a-ecgonine amide by successive treatment with ethylmagnesium bromide and m-anisylmagnesium bromide, followed by treatment of the resulting diol with zinc chloride-acetic anhydride and then demethylation. Ethyl 3 alpha-phenyltropane-3 beta-carboxylate (XV) was slightly more potent than meperidine as an analgesic.
