Ecgoninic acid

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]

The correlation of (—) cocaine, i.e., (—) 2jS-methoxycarbonyl-3 -tropanol, with l (+) glutamic acid, has been achieved via ecgoninic acid (see Volume I) recently as presented by the flow sheet (52). Accordingly, the projectional formulas used in this chapter correctly depict the absolute configuration of the natural alkaloid. [Pg.156]
