Tropinic acid

The formation of these oxidation products, and, in particular, o tropinic acid, led Merling to represent tropine as a bieyclic systen composed of a piperidine and a hexahydrobenzene ring with four carbo ... [Pg.76]

The close relationship of eegonine to tropine is brought out by its Oxidation products, which when chromic anhydride in acetic acid is the agent used are tropinone, CgHijON (p. 74), tropinic acid, CgHi304N (P- 75) and ecgoninic acid, C HnOgN. The latter crystallises from benzene in colourless needles, m.p. 93°, and has been shown by Willstatter and Bode to W-methylpyrrolidone-2-acetic acid, and this was confirmed by Willstatter and Hollander s synthesis of the acid. [Pg.97]

Now what is the most likely structure for tropinic acid ... [Pg.1025]

Structure XII was favored by Merling, for like Fischer s triacetonealka-mine, XIV (the mandelic ester possesses mydriatic properties (86)), the hydroxyl is gamma with respect to the nitrogen. Tropidine would then have an unsaturated iSmns-bridge while tropinic acid would be iV-methyl-... [Pg.280]

Tropinic acid, CgHi 30i,N, is a degradation product of atropine, an alkaloid of the deadly nightshade, Atropa belladonna. It has a neutralization equivalent of 94 1. It does not react with benzenesulfonyl chloride, cold dilute KMnOj, or Br2/CCl. Exhaustive raethylation gives the following results ... [Pg.1327]

This leads us to conclude that B is the correct structure for tropinic acid. [Pg.1330]

The entire mechanism for the formation of pimelic acid from tropinic acid, in summary, is ... [Pg.1330]
